my best reason is that it has been put on hold while i relocate myself to NYC. ironically, i have a working on that i listen to just about everyday (well, the USB needs work)
i kinda went a little nuts working the USB stack code which ended in me saying "ARGH I CANT TAKE IT ANYMORE" (july) and then it was burning man (august) and then i found out i was moving (sept), and then i had to get 100 x0xb0x's out the door (oct), and now im packing up to go (nov 1). its frustrating for me because i know if i could just find a week or two i could finish it but once a project falls behind...
ill try to get the current firmware/hardware design up on a webpage soon. probably once im at eyebeam.
if it makes you feel better, i did take two weeks to finish up the spokepov kits, and that project is literally 3 years old and people have been asking for a kit for 1.5yrs!
