Let me put in a plug for some ATM signaling code that I worked on.  It's 
called SEAN (Signaling Entity for ATM Networks) and it's a complete 
implementation of UNI 4.0 plus an API for native ATM applications.  It's 
available for free from the Naval Research Laboratory, 
http://www.nrl.navy.mil/CCS/project/public/sean/SEAN-dev.html.

If you have a NIC, then SEAN gives you real ATM.  Currently, the only NIC that 
SEAN supports is the FORE Systems SBA-200e on Sun SPARC/Solaris.  It would be 
nice to have support for other ATM NICs and for our Favorite OS.

If you don't have a NIC, you can use SEAN to simulate ATM over TCP/IP.  SEAN 
runs fine this way under NetBSD.
