I have done this with good success, by using LATCP
on the VMS system to create a LAT "application port"
and a "SLIP service".  I set the port on the DECserver
to be dedicated to autoconnect to the SLIP service.
I then used SLIP (using TGV's MultiNet TCP/IP package)
to talk IP over the pseudo-terminal.

It worked well for us, though TGV tells me that this 
configuration is "not supported" and "can crash VMS"
due to problems with the LAT driver.  I don't know whether 
this scheme would work with the Wollongong product.  (Does
Wolly support SLIP?)

Send me mail if you want more info.
