It would appear that a version of iSilo for iPhone/iPod Touch is most definitely in the works. In fact, it may arrive any minute! At least, that my interpenetration of these links I stumbled upon:

http://www.isilo.com/support/howto/T...sferFileIP.htm
This is a most exciting development indeed. I'll be watching the App Store like a hawk!
