Anyone use network storage for their photos for lightroom?

I store all my photos on Windows Home Server 1 which can be accessed perfectly easily using an MB with Snow Leopard. The LR catalogues have to be stored on a local HDD not a NAS share. I plan to transfer my LR application from the MB (it's also on a Windows 7 machine) to an iMac but I'm unsure if Lion will access the WHS as well as Snow Leopard.
