Randal,
In case it's not clear, I've rediscovered Smalltalk, and am using the numerous connections made with my friends from the open source community through the years (because of Perl) to now help promote Smalltalk. Feel free to contact me with (a) interesting projects and (b) people whom you want to reach but are more phone calls away from than I am. :)
It's my goal in 2008 to make Smalltalk have a bigger blog-buzz than Ruby. Call me crazy. But call me. :)
You, crazy!
If you have any questions regarding OLPC etoys, please ask people on the etoys mailing list (http://lists.laptop.org/listinfo/etoys). Depending on where you are going to do this kind of demo, somebody with the prototype or production model of XO may be able to help you.
