I presume that bootstrapping the startup code to Ozy could use something 
as simple as the Altera ByteBlaster (there's a reference at 
<http://opencollector.org/history/freecore/Build%20your%20own%20ByteBlaster!.htm> 
as well as a more official doc at 
<http://www.altera.co.jp/literature/ds/dsbyte.pdf>).  I've tried to find 
the equivalent for the Maxblaster, but given that a USB interface will 
be available through Ozy (this is great news, Phil.  Probably obvious to 
everyone except me!) it would seem that a really basic 'use once' 
interface is all that is required.

Please correct me if I am completely wrong - it has been known :-)
