IPC Protocols, issues

When I look at NET SHARE on my boxes I generally see one for "Remote IPC".
I figured it stands for Interprocess Communication but that doesn't tell me much.
Googling hasn't been too helpful either, but I did find a couple of general articles on IPC, not really on the Microsoft protocol or usage:

And he linked somehow to this interesting aside...
