Release: World of Goo Portable
I have created a World of Goo Portable launcher that automatically copies profiles between the host computer and a USB drive. I have tested it and it seems to work pretty well.

The main thread for it is at the 2D Boy forums, http://2dboy.com/forum/index.php/topic,2336.0.html
I have made a page for it on GooFans, but I need to have it uploaded by a mod.
Update: World of Goo Portable is now uploaded and available at the link above. Thanks, davidc!
I'll check this thread periodically for support questions and bugs, but the main movement is at the 2D Boy forums. So if you want your questions answered fast, go there.
Oh, and I'll be building in support for GooTool soon.
