Realtime Shorthand

Has anyone used Gregg for realtime shorthand? i.e. writing on a tablet pc, pda or writing tablet, having it translated by computer as you go?
I"m interested in trying that out. I like Gregg, I'm just not sure if the strokes would be distinct enough for a computer to read the different outlines.  Teeline looks a bit better, since the strokes are more distinct, but it seems Teeline is slower than Gregg.
Anyone have any ideas on this?
