Yes, this would be a good addition, we've had similar requests 
previously.  Sockets seems the best way to go, but I've never played 
with them, don't know about possible issues right now.  Searching online 
confirmed it can be done portably.

About where to look at, script links are declared in 
source/makesdna/DNA_scriptlinks_types.h and executed in 
source/blender/python/BPY_interface.c, BPY_do_pyscript and friends.  
Grepping for link events you can find places where the calls are made: 
SCRIPT_FRAMECHANGED, SCRIPT_REDRAW, etc.

Any problem, we can try to help.  You can reach BPython API development 
and discussions at the bf-python mailing list:
