Hmm, we've got some stuff that may fit what you want to do.

If you've got a real bus (Q or Uni),  we've got some high-performance X.25
cards that support, IP over X.25, X.25/X.29 connections (i.e. from/to PADs),
and a raw X.25 applications interface.

For a network,  depending on your application, you could use either use
an X.25 router (ala cisco, CMC, Retix, or (ahem) ACC).  If you want more
that IP routing (sounds like you do),  I know of one other product.  It's
a X.25/X.29 <-> TCP/IP/TELNET gateway.  We've got them,  but I dunno if it's
for sale.  If you want more than that sort of functionality,  I'm afraid
your probably S.O.L.  I had a proposal walk across my desk asking for a
box that could provide a raw programmer-level X.25 interface for multiple
hosts in an ethernet box.  I didn't think it would be fun to do,  and no one
could convince me we could sell many, so I pooped on it.

It would be pretty trivial to implement a RPC library that talked to a
Vaxserver/Decserver with a Qbus and a 5250 card.  Then you could simply
execute your X.25 calls over the network and the server would send commands
to the X.25 card.

Hope this helps.  If you want to talk more about it, drop me a note.
