I sync across a wireless bridge from my upstairs office to my downstairs entertainment center all the time. I'm not sure if it does the find-via-broadcast correctly, but it works to specify an IP for Jemplote to look for specifically.

Heh, actaully there's a bunch of netwok hardware between my PC and my empeg:

[pc]---[hub]----[802.11bridge]--/\/\/\/--[802.11bridge]----[hub]---[empeg]

Ain't technology wonderful?
