Bus pinging test on SF MUNI?

Hi there DIY San Francisco,

I don't know how many of you tune into the Discussions group on DIYcity, but an interesting conversation has emerged on creating a bottom-up pinging system for tracking bus locations in realtime and broadcasting those to others.

See beginning of conversation here:

...and continuation of conversation here:

Seeing as I used to take the 5 Fulton to work every morning back in my SF days, I keep thinking we should test this system out there. (Knowing when that bus was coming in the morning would have saved me a lot of time and headaches).

I was thinking a limited test on a single bus line would be a good start.

Is anyone interested in this?
