I don't think DLSw being SNA only is a problem.  I say this because I 
think DLSw requires TCP/IP connectivity.  Thus you already have TCP/IP 
connectivity to the mainframe.

Is it proper to say that SNA is the protocol that is carried across the 
DLSw over IP?  Is it also what's carried over the SDLC?

Okay....  I'm lost.

If there's no Cisco box with Twinax and the host doesn't have TCP/IP, 
how are you going to connect things?

SNA across Token Ring and / or Ethernet?
