I think Roland has done something like that for NaCl testing. I've done
things like that involving a complicated set of scripts to send commands
over a socket to allow a DejaGnu board file to be used for running tests
from non-DejaGnu testsuites, but not anything convenient to use in a
standalone way like cross-test-ssh.sh.
