I hope there may be some changes in attitude towards virtual worlds. My colleague Will Pollard often claims that the time is still not right, that UK broadband is not Twinity ready or some other reason based on normal opinions.
But I notice he has tried out placing sculpture on a beach. I know that Web Kirby has been suggesting Twinity as a base for a gallery. Now there is 3D printing it should be possible to move models in various ways.

If this works ok then a conference in Twinity could be next.
