I should note that I haven't played with it myself, but I was pretty
thrilled with the idea when I first saw it discussed at a Xilinx seminar
about a year ago.  I should get off my ass and get it...

something like $100 when you bought the Multilinx cable, which is needed
to use it.  Still, though, even after you spend $500 or whatever the 
Multilinx cable costs, it's a damn good deal.

It'd need a fundamentally different approach than that taken by Xilinx, 
I think.  If it's anything like "probing" using Foundation's FPGA Editor,
the nets are specified and probed *after* PAR, making it a technology-
specific thing.

It would certainly be a win to move it "upwards" in the design so that
it's easier port to different manufacturers.  More information is needed -
has anyone on-list used it?  Are any of the other vendors doing anything
similar?
