cross-language testing

[mtib]

we should write a suite to test if our HEAD versions can talk to each other. This would probably work by sending a (one off) message via flags or setting the suite up via environment variables

CHATDE_TEST_MESSAGE="Hello World"
CHATDE_EXPT_ANSWER="61FB749F83E696C248ADD1D88F77C6E1DED0"
CHATDE_TEST_MODE=true
CHATDE_TOFILE # ??? To emulate writing to wire | use file
(
  gochatde -cross-test -debug localhost
) & (
  delta-l --cross-test --debug 
)

... thoughts to be had
