If you haven't been keeping up with mod_perl development lately, then you've been missing out on a lot. There was a Christmas release (2.0.0-RC2-XMas) which I have just upgraded to. Mod_perl 2 has been in development for over three years, and if you haven't tried it yet you should download the release candidate and test it out.
I've been reading a lot of positive reviews lately about OpenInteract. They have a 2.0 version releasing, so I am going to evaluate it on my mod_perl2 x-mas release candidate tonight. I'm hoping it will provide a scalable platform that will allow me to concentrate on classes and application logic. I always end up tweaking my mod_perl application servers a bit here and there, but I guess that's part of the fun.
