Multiple SMPs: Sharing resume point for videos on network

I have videos on a networked shared drive.  If I were to have multiple SMPs on my network is the resume point/time stored on the network such that it could be shared among all the SMPs?

Only for DVDs, since the SMP saves individual resume point files for DVDs.

Where are the resume points for other videos stored?  If in the “database”, it seems they still could be shared since it is on the network?  Thanks.

If only ONE device is powered up at one time, you might get lucky.
