I'm not sure how many of you are aware of chromatic's previous article about "5 things perl 5 needs right now", or about the mod_perlite project that was spawned by some people from sixapart, but chromatic has published another article that's basically a conversation with Byrne Reese and Aaron Stone, aka the guys at 6A that are/were working on mod_perlite. Anyway, it might be interesting to some people on the list:
http://broadcast.oreilly.com/2009/01/cgi-is-dead-mod-perlite-is-ali.html The project is supposed to basically be mod_perl's registry only, packaged such that it would be possible to get mass virtual hosting providers to install it. The core motivation being so that 6A's Customers running MT in that architecture can get better performance. The difference between it and FastCGI being that you can run unaltered code originally destined for CGI, just like Registry or PerlRun. Adam
