First of all thank you for a great app. It is very easy and intuitive to use. I was playing around in CloudParty Virtual World and looking for a quick way to develop and furnish home there. I came across this app and thought I would give it a try. To test it, I took the number one Example Home from the Gallery page and ported it over to CloudParty. Surprisingly it was quite easy to do. I exported to obj, imported in Blender , exported to collada and imported it in Cloudparty. I have setup the house on a free land provided by CloudParty.

For those of you who may not know CloudParty is a virtual world which runs completely inside the browser. It uses no plugin and instead relies on HTML 5 technology alone. I think it can be a great way to show case your SweetHome3d creation.
