same here. only http; nothing else can penetrate, not even httptunnel.
Only issue is, integration with irc. I've actually had a few ideas on this topic, and the best i came up with is as follows:
have a forum mod; probly a modified shoutbox like deal
it displays the last 30 or so lines from #outpost2, and features a box for input. you click button, it submits the text and ur username to a php script running on OPU|Bot, which puts it into a text file.
every 10 or so seconds OPU|Bot runs a TCL script to dump the contents of said text file into irc, delay 1 sec/line ,max 6 or so lines
crude and slow at best but it'ld work.
