There is another fragmentary Sixth Concerto, also in D major, the first movement of which has appeared in a performing edition by Professor Nicholas Cook. I have only encountered it in MIDI format on the "Unheard Beethoven" website: http://www.unheardbeethoven.org/. It's interesting music, in a post-"Emperor" mode, and is definitely distinct from the Violin Concerto. DPHorn, who wishes that Beethoven hadn't put it aside.
