Would "certan circumstances" be such where the data transfer consisted
of multiple data streams? (Like download accelerators and p2p
clients?)

Comcast might have a cap on the throughput of individual TCP streams.
Seems likely, especially if they expect customers to have more than
one simultaneous user to a particular account. It would certainly make
for an easy way to keep one user from hogging all the bandwidth, and
thus reduces complaint calls about "My internet is slow!"
