So the easiest(and most secure by using an established partner) way to realize this without even having to host a website would be hosting an OpenSim with OMC (https://www.virwox.com/omc-open-metaverse-currency.php) and in fact just let people exchange their BTC for OMC at virwox.

Of course that doesn't make this project unique in any way other than trying to keep the community bitcoin.
