mod_tcl is not an option. As I've said, I've looked into the problem somewhat.
Getting a robust implementation working under Apache would be a large implementation effort. My background is in compiler writing and operating systems work (mostly old ones, like the original 1974 version of Unix from Bell Labs), so I don't see it as impossible, but certainly not trivial.
Don't worry, I won't sugar coat the effort involved.
As far as what sysadmins should talk about at an informal meeting held at the conference, I'd suggest they should talk about anything they'd like to talk about.
