mod_perlite
Another ‘embed Perl in Apache’ module, this one trying to get rid of the thing that makes mod_perl so great and awful at the same time - the persistent run-time. It seems to be that this is an odd time to produce such a thing - the recent trend seems to be towards even small projects having a lightweight front-end server like lighttpd or nginx, and a specialised back-end server like mongrel.
