Great to hear!  Now I'll just need to figure out how to submit the fix
as a patch to MICO...

I see a couple of problems with it, I've listed them below.

What do you mean by local invocation?  If you give the client a
reference to an object on the fixed network, it should invoke on that
object.  But if you use the configuration below, your applications
never actually consider themselves to be on the terminal, since they
don't get the option that triggers the 'unplugged' mode.  So if by
local invocation you mean that the invocations don't go through the
bridges, that's probably the cause.


And here are the comments on your script:

You seem to be running these only on the Access Bridge host.  You
should not give these addresses to the Terminal Bridge, they should be
local to the terminal.  So you should have (at least) two instances of
both running, ones on the terminal and ones on the fixed network.

If you're running these on the terminal, based on what you do below,
you'll also need the option '-ORBConfFile ~/.miwcoapprc'.  But only
give that option on the terminal.

If you're actually running the HLA, you'll also need the option
'-ORBInitRef HomeLocationAgent=`cat home.ref`', for both the tb
execution and in the ~/.miwcoapprc file.

Also, you need to build the ~/.miwcoapprc file after starting the tb,
since the last line of the creation of that file should have
'MobileTerminalBridge=`cat tb.ref`' instead of having home.ref.


Getting all of this to work is quite a bit of work, I know, and I'm
sorry about that.  It just was never a priority to design how to
configure the thing, just implement it.
