I use the 'pyephem' module in python to do this kind of thing. Its not a nice finished product, just python scripts with terminal printing, but it basically looks for periods of time when there is positive elevation at both sites for a given target (not just satellites, but moon, planets, etc.).

Is anyone aware of a tracking program that will predict mutual windows between two points on all satellites in a group or file, rather than one at a time? I'm aware of and use SatPC32's excellent WinListen, but as far as I can tell that's only one at a time.

Thanks, Drew KO4MA
