This is a good idea but people should understand how ToonTalk names the
files needed for an applet. The images, sounds, and robots should all
have unique names (or in case of collisions be the same sound or image).
The main applet file name is generated by ToonTalk if there isn't a
short text pad on the back of the picture. The name generation is unique
only from that machine so there should never be a conflict between two
applets generated by the same computer. Except if the user provided a
name, e.g. "My Simulation" and others picked the same name. Name
conflict for unnamed applets generated on different machines may
happen - but hopefully rare enough not to worry.

Jesper - Regarding ttclass2.cab, how hard would it be to overwrite only
if the creation date is later? There are several versions of
ttclass2.cab and the most the recent is the best. When there is an
incompatible change then there will be a ttclass3.cab and ttclass3.zip.
But that has only happened once in six years so we probably don't need
to worry about that.

I think we should leave things in both ToonTalk and the Plone as they
are but watch out for any problems. And encourage users to give names
that are likely to be unique.

Best,
