If your requirements are voice/video, you're pretty much out of luck. If 
you are only interested in text chat, Pidgin is pretty good.

The total memory used from what you listed above is about 200MB - that 
isn't TOO bad. There are ways to squeeze a bit more memory out of the 
AC100. You can scrape an extra 62MB of RAM out of the frame buffer which 
makes a non-trivial difference, and there are ways to get a bit more out 
using zram for swap, zcache, reducing the default stack size, etc. Have 
a look here:
