I just did some quick training on it a couple days back and our first Escient FP-1 arrived today. For those not in the know this is a Escient Fireball music server that uses your I-Pod as the storage device. You just pop it on the dock and then you have access to everything on it via the Pronto Escient interface (or Escient's own web server or TV out/remote control interfaces).
This is one of the items that sold us on the Pronto at CEDIA and at the price of a FP-1 adding to your system is a no brainer.
