The brasilian PM groups are talking to build one kind of pseudo-interactive-perl-shell by web. The idea behind this pseudo-shell-interactive is to create e-learning course of Perl, where students will could do classes exercises direct on her/his web browser. Our first course will be PerlIntro.POD translated to e-learning course.

We think this could be very nice for Windows users, and for someone that just would like try Perl.

Well with this idea, now we are talking how to implement this on real world, and divided this implementation on 2 possible technology, as :

* Server-side
Where we will use a web browser (with JavaScript+AJAX) just to get the user command and run this command on Perl instance install at server.
Here we are afraid about security at server (there is a way to run this remote code in a safe way at server ?) and how big will be server to run many interactive users ?

* Client-side
Where we will use a web browser to work as pseudo-shell-interactive, embedding Perl on a Java Applet or other stranger technology.

I would like help to figure-out one good way to implement this pseudo-interactive-perl-shell by web, or just say "Don't waste time with this stupid idea :( !!!".

Thanks,
