Unfortunally, the Google App Engine [http://code.google.com/appengine/] only seems to support Java and Python.
I wonder if [Jacl] helps us?
[NEM] 2010-01-08: Yes, [Jacl] (or the [TJC compiler]) can be used to deploy Tcl applications to Google's app engine
(technically, at least -- you'd have to check Google's terms of service). An example servlet that should work follows.
This simple servlet evaluates any arbitrary code that you pass in the ?script= parameter (e.g., script=puts+%22Hello,%20World!%22).
Obviously, don't deploy this to a production server!
