Not OSS, or even free, but Terrabrowser sounds exactly like what you're looking for. $15, cheap enough, esp. for a Mac program. It's a sweet program, I use it a lot for USGS data, and I just purchased a GPS interface and I'm looking forward to trying it out.

I've got my Garmin Vista talking to my OS X box via a Keyspan USB to serial cable and run the freeware GPS Connect and its shareware big brother Terrabrowser to upload and download waypoints.

Might you possibly mean TerraBrowser? Yes, the images are outdated but it's still fascinating to look at terrain you know today as it appeared over a decade ago. A little like flying around in a time machine.

if you don't need all the features of MacStumbler, you can try the very nice AP Grapher to track signal strength.

If you have an Apple, check out AP grapher for OSX

They have links to other stuff as well, and also the Apple headers - so you could develop your own too... But this is good stuff for looking at Wireless links...

There is no GPS software that works on a Mac... Riight...
