I was thinking about this again the other day.
you can put 24bit files on the Jb3 aslong as there under the 2gb limit.
with a third party driver it would seem that the Jb3 could be used as portable HD and be used VIA lappy/IPAQ > Firewire > JB3
I would think we just need someone to write a driver for it to be able to record VIA firwire. as it can play VIA firwire ..
