You can have SDLC and TCI/IP coexist on your WAN as long as your routers
will handle it.  You don't have to encapsulate one into the other and take a
performance hit.  This way you have both up at the same time, native, and
migrate your apps off SNA at your leisure (if there is any such thing in
this business).
