Ahhh.. Then yes, that would make a significant difference. :)

Yes, it's LAT that needs to be bridged. I left that out of my original
question because I didn't think it was relevant, but it turns out to have
been.

Was there anything in the original question to indicate a DECNet oriented
solution? (I may be a bit tired, but I didn't read that)
http://www.protocols.com/pbook/decnet.htm
I agree with Brian for bridging over Frame Relay as the most obvious, and
with Joseph (and someone else I've forgotten (sorry)) about the L2TPv3 as
the second solution.
Just my two cents.

I just found the answer. LAT to LAT across an IP WAN.
http://cisco.com/en/US/docs/ios/11_0/protocol/command/reference/pctrans.html
#wp1680
It translates the LAT into TCP and de-translates at the other end.
Bridging across multiple routers and a WAN link could get icky.

Maybe I'm missing something here but why can't you just "bridge"
across the FR connection?
