Another reason why PSK31 is so popular is that it's easy for developers to add support, it's the basic digital mode these days (along with RTTY). There are several open source implementations available which cover Windows and Linux.
I haven't been able to keep up with Patrick's work as I have been to involved in getting some other basic software written; for ARQ modes such as FAE 400 to be adopted we need to get a GPL source code available so that it's easy for other developers to add support. Myself I'm not too interested in the emergency comms side of things, at the moment more the normal chit-chat QSO modes. I must say that Patrick has excellent ideas.
