Hmmm, I have a very simple /proc driver that just list out the KIP for now.
and I was thinking how to extend it. I could add a char driver
implementation, but then doesn't IPC look more like a block device, or
really even a network device?  I guess one advantage to a char driver is
that then you can write userland PERL, Scheme and Ruby programs that could
talk to Iguana Servers very easily.



Did your /proc driver allow userland threads to write into parts of it? I'm
just curious how you went about it?
