Hi Matt, Thanks a lot for the offer. It's heart warming to hear people proposing improvements.
Unfortunately, across the past years, we have not been able to make the HMM functionality respect our own guidelines. The core problem is that HMMs are intrinsically a structured data learning task, that does not fit in the general framework of scikit-learn. Of course, this is a limitation of scikit-learn, but time has told that we cannot broaden the scope of the project as the project is already very wide. Thus, we have decided, after hesitating for a long time, to cut off the HMM code and move it outside: http://sourceforge.net/mailarchive/message.php?msg_id=31726218 The work of moving the HMMs outside our codebase to a new github organisation hasn't started yet. If you want to give us a hand with this, and merge in the new package your contribution, it would be fantastic!
