By way of background, I've got 3 Macs all running Lion all containing folders that I'd like to keep synchronized.  I've used a combination of Powerfolder, DropBox, and Zumodrive (the latter 2 to enable collaboration, access on my iOS devices, etc.) to do this, but I was hoping to consolidate to a Pogoplug.  I've purchased a Pogoplug classic (not interested in media sharing) and have a drobo raid array attached to it.  I've tried using the "regular" pogoplug software as well as the seemingly newer pogoplug browser software.  Other than 1-directional backups, the former didn't really seem to have a sync function.  The latter "sort of " works if using a single computer to synchronize folders with the pogoplug (it doesn't seem to sync deletions, thus acting like a back up rather than a true sync).  However, I cannot get multiple computers all pointed at the same folder to sync.  Any thoughts?  I'm a bit surprised this doesn't work out of the box; many products do this pretty flawlessly (aforementioned programs, plus sugarsync, etc.).  Thanks.
