Ahh, but that's just you, and not really coda as a whole. I know way back
I had problems getting a server going, too, but I haven't tried recently.
Once the 2.2 kernel comes out and I get Ethernet access, I'll attempt to
set up a full-time coda server and see how much it has improved.

Peter said at his LinuxExpo talk that it trickles back according to the
available bandwidth...

Mostly an implementation issue - use of C++ doesn't help matters I
suppose, and it wouldn't hurt to run coda through purify once or twice...

What is it with these people that keep repeating "raw device, raw device" 
as if it were a magical divination, but have never heard of fsync(), which
gives you (compared to raw devices) great performance _and_ guaranteed

Your FUD is funny :)

The builtin security is waaay better than what NFS has - it's obviously
not perfect, but
