Interesting idea. I'll look into that.

Alas, this is cable. I'd love to get Linux-friendly SpeakEasy but I'm in 
older housing that's too far from the CO. But thanks for the enlightenment 
about Interleave vs. Fast Path. Something to consider if they ever get one 
of those "CO's in a box" installed in the street closer to my home.

I believe it's using the Wondershaper from http://lartc.org/. Shaping is 
done outbound, policing inbound. Shaping is done by setting the actual 
outbound bandwidth and not submitting packets to the interface faster than 
that. That way they don't queue up in the modem but instead in the Linux 
HTB buffers where they can get prioritized. Once the packets are beyond my 
router, I can no longer guarantee that my game packets get to skip the line.
