So I got bored and started working on an aim client written, you guessed it, in perl. It's console-based and will eventually be very similar to tac, but better. Eventually once I get some bugs and basic features nailed out I'm going to attempt to write both Gtk2 and Curses::UI front-ends for it.

Right now it supports the most basic of features including logging in, messaging, receiving messages, get user info, and aliases. Aliases can be nested, that is you can do:

/alias foo /msg psikronic
/alias bar /foo Hello!

and then call /bar and it will call /foo Hello! which will in-turn call /msg psikronic Hello!. Huzzah.

I also added a /default command which will set the default target to send messages to. You can also do ; some message text to message the person who messaged you most recently (prefix the line with semi-colon). You can also do /default ; to set the default to the person who most recently messaged you.
