Updates are over serial Connection UART at the minute with TCP/IP remote
update planned shortly. In fact we plan to support dynamic updates over
almost anything that can communicate with the uVM device. Also plan remote
in place debugging :-) But the wishlist is pretty long so what comes when is
trickier!

BTW - THe uVMDK is now available for download and device samples are
available immianently when I will make a more general announcment.
