> TCP implementations of OS's today have been tuned for the late 90s,

Here's where you need to slow down and think for a moment before you re-invent TCP.

If you "retune" everything for broadband, you're crippling your ability to reach your emerging mobile audience, whose TCP metrics look for all the world like dial up and ISDN of the late 90s.

Actually they don't. Dial-up is low bandwidth, low latency. Mobile is high bandwidth, high latency.
Dial up is low latency when a modem adds 200 ms by itself?

Mobile is high bandwidth when an EDGE connection might pull 110 Kbps when the rural user is lucky?

Either you're confused, or talking about different tech.

Closer to 100ms and, more importantly, constant not variable.

The fastest modems sold were 56kbps.

I had ISDN in the 90s, at dual 64k.

Was in ISP business since early 90s, and in streaming business since before broadband, so familiar with connection profiles, latency, and effects of tuning TCP. There's a lot of lost or forgotten art being reinvented or rediscovered for today's mobile.
