Hi,

i've just created a List of Commercial Projects using Squeak 
on Squeak's swiki.

You can find it on http://minnow.cc.gatech.edu/squeak/2628

As stated on the page, one of the intents of this list is to 
have some reference use cases, something very useful for 
people who is trying to sell their clients a project based 
on Squeak.

And of course, if you have a project to add to the list, 
just add it.

Cheers,
Federico G. Stilman.
