Turbo looks fantastic, though! It's precisely the niche I was looking to have filled, so I'll build a prototype or two in it to see what I think. Very much appreciate the pointer!
TurboLua is particularly great because it really integrates about all of the I/O mechanisms you could want in a network-centric application, plus it has a pretty nice runtime loop which is easy to hook into and coordinate properly with signal handlers and fd sets and things. Can’t beat it as a very quick way to do embedded stuff too - very easy to do gpio, signal handling, etc.
Good luck, if you have time to share your thoughts after an initial first-pass, I’d be happy to hear your perspective ..
