Actually, I should have said two-way communication was difficult.

Right.  All I ever really wanted to do on the LAN was connect two Windows
bridge-playing programs, but they can't find each other.  Now that I think
harder, what it really needs is port redirection.  Your wireless router is
set up so that incoming requests to port X get sent to machine Y - and
that's what has to happen for the Host, or other machines on your LAN, to
initiate conversations with the guest.  That would be fine for my bridge
program, but impossible if I'm trying to run programs on both the host &
guest that use the same port number (but then, you can't run two programs
on the same machine using the same port, anyway).

That's as it should be - the VM is on its own subnet and the shared network
is the _host's_ network, so there is only actually one 10.0.2.15 address
per network.
