core/doc/GUI_SPEC - full docs for the UI comms protocol. You can try it 
out with the simple client in the core/GUIcomms/ directory, although 
the interface is a bit arcane. The source is probably your best guide 
for that. Writing a better (more user-friendly) UI tester is a job I 
have lined up for myself sometime - shouldn't be too difficult (famous 
last words)...

Right. The cookie is all the access control we have. It's 8 bytes of 
random data, made up as the core starts (unless it's specified on the 
command line with the --cookie option). When a UI connects, it sends 
these 8 bytes as the first thing it does. If they're correct, normal 
commands start being sent. If not, you get a {"cookie_rejected"} and 
the core drops the connection.
