cue sales pitch
NXT is cool as far as minimal protocols go, however I can't find a client besides the java one (which is obviously not embeddable). Is there sourcecode for nxtsolaris somewhere?
Ummm....probably. If you're serious about this, I can chase some devs up for you.
Marcus03 was the dev for NxtSolaris:

I suggest you post your needs here:
