Hi Yoshiki,

None, really. It's a concept demo so whatever works, works. The only
issue is that the PC must be a windows machine because it uses some
weird library which is not available on other platforms.

This would be about perfect. But is there any such hardware available
for the iPAQ?! And how does one use it - is it just like any other
network?

Well, if the iPAQ part works I can surely make the Win part happening
;-)

This would definitely help. Not all of the data is images but a large
part is so using JPEGs could make a real difference here. Are these VMs
up somewhere?!
