katrex,
Don't know if this died or not, but I think it'd be cool. I was thinking of a playing a former fixer turned technomancer/face. He was just starting to make a name for herself in Atlanta (or insert city of origin) when she emerged in the middle of the 2071 (if I recall the date correctly, whenever Emergence is set). He tried to hide who he had become for as long as she could, but people find out everything in the shadows. Losing Johnson after Johnson, he finally gave up and shipped out, using the contacts that would still talk to her to set up as a runner in (insert city we'd be running), as well as finding someone (or something) to guide her on this new path.
Mechanically, I'd build heavily into social attributes, connections, and a stack of cash. Skills would match, with either a lot of low-point technomancer stuff or a narrower, higher value pool (haven't decided)
