The answer is "yes, provisionally".

It depends on how you are sharing data between the apps.  I believe
pipes and sockets will both work, shared memory depends on the packing
and ordering and alignment from both machines on the dsata in the
shared semnet, and SYSV IPC probably won't be happy (just a gut feeling,
since no one is doing a lot of this).

They'll definitely run dsimultaneously -- and Linux, and NetBSD and
FreeBSD binaries, and DOS (under PCEMU) and Windoes (under Willows)
and Mac (under Executor under Linux) and Commodore64 under the XC64,
and...
