I'm new to this discussion but it seems that you should take a look at
Java ( It has all the features of Safe-Tcl, it is
secure, the performance is better, and it is freely available.

Isn't TeleScript like Tcl but with postfix notation? Isn't TeleScript a
propriatery language?

I believe that Acrobat only supports PDS, but I may be wrong. PDS is
not a full PostScript language implementation. It only supports the
graphics primitives. For a language to be useful in a WWW browser you
need much more that a "full" language. You need a complete
infrastructure for embedding, security, internet libraries etc.
PostScript is not appropriate for that.
