I saw this pop up in the vwnc mailing list:

We are proud to invite you to a small meeting of Smalltalkers in Prague, which will start Thursday 5th March 2009 at 6pm in Rainbow tearoom in Prague, Czech republic. Janko Mivsek promised us a presentation of Swazoo & Aida web technologies, which will be the first part of meeting.

Sounds like fun - I'll be heading home from Cincinnati at the time.
