Dumbfounded Over Davidic Dynasty

I've been seeing huge ads in the Jewish papers for a while now proclaiming the new foundation called the Davidic Dynasty. I find the whole thing a bit bizarre, so maybe some of my readers can help me out. Apparently, those who have a oral family tradition of being descendants of King David are joining together to...join together??

The website doesn't make clear what the objective of the foundation is - though it does make some amorphous references to sovereignty over Israel:

At this critical time when the world questions
Jewish sovereignty in Israel

The Eshet Chayil Foundation

announces an Historic and Majestic event
to declare our Eternal Right to our Homeland
and restore Jewish Pride
in our Glorious Past
and in the promise of our Future...

I just don't get it.

Apparently, this Jewish version of a blue blood, white shoe, members-only club even has levels of membership based on having the correct lineage:

Join the Davidic Dynasty through these distinguished membership categories:

1. Royal Membership
If you have an oral tradition (mesorah) and/or genealogical data showing that you’re a Jewish descendant of King David, and you want to support the historic reunion of Jewish descendants of King David in Jerusalem, the City of David in May of '07, then you are invited to become a
ROYAL MEMBER of the DAVIDIC DYNASTY

2. Loyal Membership
If you are of the Jewish faith and appreciate the importance of uniting the living descendants of King David in order to send a vital message of Jewish pride and unity to all Jews as well as to all nations of the world and to declare our Eternal Right to our Homeland, then please join us as a
LOYAL MEMBER of the DAVIDIC DYNASTY

Let me get this straight. If you have a family tradition of being descended from King David, you get to become a full member, otherwise, those not as well-born can become one of the loyal minions.

Of course, in this era of litigiousness, what would a new venture be without a page of small-print disclaimers. And the Davidic Dynasty doesn't disappoint. A taste:

1) "Davidic Dynasty" cannot confirm or deny the accuracy of a claim to Davidic descent, In fact, "Davidic Dynasty recognizes that there is no irrefutable proof of claims to Davidic Descent.

... 2) Research may show that certain families claiming Davidic descent are not in fact descended from King David in the manner which they claim.. "Davidic Dynasty" reserves the right to present such research even though it may contradict the claim of a particular family

3) While the team of genealogy research advisors will do its best to examine claims of families to Davidic descent, no responsibly is taken for the veracity of such claims.

4) "David Dynasty" will attempt to present the various opinions of genealogy researchers as to the means of descent of families claiming descent from King David but will not specifically endorse any of them.

5) In the event of conflict between the opinions of genealogy researchers, or sources, the opinion expressed by "Davidic Dynasty" is that of its committee of genealogy advisors. Should there be disagreement among the members of the committee, the chairman will make every attempt to arrive at a consensus, but in the final analysis, the chairman retains the right to use his discretion as to what will be presented on the site and at the Reunion.

Ok, we get the point. You guys are a club, and we have to have be descended from the "right people" to join. Even if we have one of these names, you guys can decide that we aren't really up to the snuff of being royal instead of piddling loyal members.

The group is even trying to create a DNA test that would prove that someone is in possession of Davidic bloodlines.

But seriously, what is the objective here? A large family reunion? I don't personally see why being a co-descendant of a man who walked the earth more than three thousand years ago (King David) is any more of a strong connection than being co-descendants of a man who walked the earth more than five thousand years ago (Adam). Is this about declaring a new king? According to this, clearly not (from those disclaimers again):

7) Individuals claiming the right of succession to the throne of King David or the restoration of the Davidic Monarchy will not be endorsed or acknowledged in any way by "Davidic Dynasty".

So what is this all about? Can someone please enlighten me?
