I suggested something similar to this also. I started a post a few weeks ago with referrence to a version of mirc meant just for usage as bots. No gui, just the process running in the background as do eggdrops with the ability to use most to all the commands as mirc version 6.12
I can't really imagine the mirc language expanding beyond it's use for IRC, however it's very possible. However many people do use the program to run 'bots' and I believe a version much to the ressemblence of eggdrops with similar reliabilty and much more easily scripted would prove to be very popular among coders and very helpful to members of the irc community.
P.S. If you support this idea, post your thoughts here
