Yes, it would be nice to have several versions of Perl around, just to experiment with them.

tons of CPAN modules

You would probably need more than a single CD for that. Even CPAN::Mini creates a minimalist mirror of the CPAN that has over 440Mb ATM.

some IDE like Eclipse/EPIC

I disagree with this one... but that's me :-) YMMV :-)

lots of sample code

Er... OK, but this probably wouldn't be easy to come by, unless of course we'd choose a section of perlmonks and copy-paste it there, or something (you'd get the comments, which could be good).

links to websites

Sounds like a nice idea, yes.

a few HTML pages that explain how to access it all, etc.

Actually, I think this might be a very good idea... Do I see anyone volunteering? O:-)

We were thinking of getting a company to sponsor some CPAN cds for YAPC::EU::2005. Perhaps a small team could assemble a bunch of useful stuff and, provided we do get a company to support it, we could hand those cds over (not only to conference atendees, of course).
