I spent a fair amount of time playing with these last night but I
didn't find a solution. I'm still thinking about it, but I believe
that most likely it will require some scripting in Lua (or another
language) to be able to get this to work. This is the first time I've
ever dealt with keeping the b-leg alive when the a-leg hangs up - it
is usually the other way around.

I recommend you read up on Lua scripting because you're gonna need it
to be able to pull this off. (You could use a different language but
Lua is the scripting language of choice amongst the FS devs so I
highly recommend using it.)

I will tinker with this a bit later today when I have some more time.
In the meantime if you could start experimenting with the ideas you've
presented and brush up on Lua that would be great. BTW, are you on
IRC?

Thanks,
MC
