It seems with what the Lynx is already capable of doing adding a shuffle via a software update would need not be hard to pull off considering the Lynx already buffers your favorite music stations to allow for the tune start capability.
Using one of the playlist slots you would start your shuffle. As the songs are pulled from the buffered stations you could thumbs up or thumbs down whatever song is playing. Thumbs down kills that song from being pulled into your playlist in the future....
