While it is true that the DroboShare offers network functionality like the Droboshare desktop and DroboShare apps there are other alternatives.
You can of course hook it up to any PC via the Firewires/USB/eSATA connector and share it, but that can be a costly solution if you do not already have a server up and running.
I recently moved my Drobo from the Droboshare to a TonidoPlug computer. A small, low watt server with support for up to 8 usb devices (via a hub) as well as all the cool Tonido applications the plug supports natively. For the $100, it is a very cost effective solution that allows the drobo to be accessible from your entire network. Half the cost of a new DroboShare and only slightly more than they go for used.

I even have mine tied to my Crashplan through my TonidoPlug.
