Yes, Space Taxi on the Atari 2600 would be a dream come true. That game was my all time favorite game on the C64 and I spent way too much of my life playing it, both then and still now.
For all that would be interested, this company has hooked up with John Kutcher to make a official sequel to the game on PC.

Also, this site has a C64 emulator that runs on Pocket PC's and I was just playing a game of Space Taxi just a couple of minutes ago, with it.
