Hi David,

Urgh, housebuying... my favourite reason for procrastination.  ;)

Sounds interesting - may almost certainly be pads for one if it's not 
fitted.  Unless they respan the board and removed it.  SMC is a bit 
nasty though, I can see why you'd prefer USB storage devices!

I've been wondering this;  I have no experience with USB whatsoever 
though.  It could be that porting something like Redboot might be a 
better idea than what I'm working on ;-)  But Redboot and IIRC U-Boot 
have USB support.  Of course if it's easily separable both are GPL so 
we could reuse their USB stuff!  It's likely not to be too compact
