I am actually quite surprised that this has not taken off faster than it has already, what is stopping this from exploding? I haven't reviewed the code, but there does not seem to be any complaints from current users, so why has it not gained extreme attention?
Two reasons:
1. The software is still a little buggy, not in ways that should lose money, but in ways that make the client hard to use. I have yet to fix some annoying crashes.
2. Until the OP_CHECKLOCKTIMEVERIFY changes are adopted by each coin, there is a TX malleability attack that can let the counterparty steal the funds that should have paid out to you.
I'm working on building out all the code, so #1 should not be a major issue for long. But #2 waits on the coin developers to merge the OP_CHECKLOCKTIMEVERIFY changes. This is very likely to happen since a lot of other protocols rely on this change, but all I really can do is wait.
