Palm Store - Wireless Keyboard

Palm Store - Wireless Keyboard: "Model Number: P10946U One keyboard that works with all current Palm" Yes, that's all very well and good, but does this work with the Treo 600? I would assume so, since its an IR protocol, the Treo 600 has the right OS, but is there something that is inherently missing from Hanndspring (a.k.a the bastard stepchild of Palm) that is in the PalmOne devices. This enquiring, and somewhat fixated on wifi, mind wants to know...
