My top choices:

AI Exploration in Perl
Perl is too slow for AI programming in general, but it's a great way to explore basic concepts and perhaps whet people's appetites.
Perl for Students
Build simple dynamic Web pages. Download music. Post to your blog. Tell the RIAA to go stuff themselves.

And while I don't know that it would make an entire book, more information about using chromatic's P5NCI would be great. It would make it much easier to use a lot of existing C or C++ code for the traditionally slow bits of Perl.
