As I remember, I didn't have to do anything special to get it working using
the Ultrix DLI.  I asked for UAB when I ran Configure, did the make, 
installed it, created the bridge_desc file, and away it went (after a
couple of fixed typos, and getting things started in the right order).
We already had CAP running on other systems (Suns) here.

Yes, it really did run that much faster.  My test was to copy a file
(~200k) from a Mac to my DECstation 5000's local disk.  With Jeff's
packetfilter mods, it was about as fast as our Sun Sparc 2 CAP server,
which is running Rutgers CAP.  CAP+Ultrix DLI took 71 seconds,
CAP+Ultrix pfilt took 5.  I was suprised by the difference, so I ran
the test several times to make sure.  I was running the following
CAP daemons:  uab, atis, aufs.

I'm no Mac/CAP/whatever-talk expert, so I may not be able to answer
some questions about CAP and Ultrix, but I will try.
