What is the diffrence between the green and black listings for speed while searching. I've noticed both colors under all types of connections (Modem, Cable, T1, etc.)

I /think/ that green means that one or more (if they are grouped)of the hosts has at least one free upload slot at the time of the query.

It is only a vague indicator of the likelihood of being able to connect to them to download a file.

good guess, but green actually indicates a more accurate host speed, while black T3 most likely will be a modem host.
