Personally I think multiple owners would lead to quite a mess one day. The same goes for a corporate owner.
Instead I would agree with donating to a fund to buy the site, electing a new administrator, turning it over to them with an agreement/contract that the site/property would be relinquished back to the community if they decided to step down so that the process could be repeated if needed.
I don't know if thay type of arrangement fits the non-profit model AmigaDave is proposing or not.
Oh, the wife will trounce me, but put me down for $100.
