Sharespace & Mac OSX Time Machine

Is it possible to configure a WD Sharespace so that it can be used reliably with Time Machine in Mac OSX?

From what I can pick up on the internet, the drive is not recognised by TM straight out of the box but it is possible to get it to work (changing paramenters on the client Mac, I think).  There seem to be questions realted to  relaiability of the backups however.

Can anyone offer any further guidance or experience?
