Is this being looked in to recently? There is a bugzilla entry (Bug 18424 – Remote device wipe for windows mobile and iphone devices), but it has not seen much action. For this to be used at an enterprise level, I would think a way to clear all sync data would be essential. Untold amounts of information could be lost if a phone or PDA vanished.

Please look into it so that my execs can feel a bit more secure about using it.
