From what I recall, this forgotten (but nice) phone has an encrypted bootloader like other Moto phones.  I'd like to start a project to hopefully get by this and allow custom recovery/roms.  However, I'm not sure how they unlocked/bypassed the other phones with RSA(?) encryption.  If I knew this, I'd have a place to start.  Could anyone here point me in the right direction?

There was apparently some effort at doing this a while ago, but it appears that nothing came of it. 

In the meantime...Since the phone has long since gone unsupported...I wonder if I can get a hold of someone at Moto and ask for the key?  I figure the chance of succeeding is less than 1%.  I'd still like to do it the hard way, mostly as a learning experience.  No harm in trying...perhaps when I get free time to put together a well-thought-out message.
