I guess "instantaneously(sp)" is relative. I just watched VFP freeze for 15 seconds before it returned -1 when I typed:

? diskspace("\\noserver\noshare")

I think diskspace() depends on the config of the hosting machine.

I still think using something like running IIS on a the data server, installing an "I am alive" page, setting the timeout on the VFP/wwIPStuff client side to 3 seconds, and then polling for that server page would be faster.
