Ok, I was curious and sniffed the SYN packets to my client (LimeWire)
for about an hour (not very representative, I know). The average was
about 9 packets per minute. Assuming 48 byte per SYN packet and
20 byte for each RST makes 10.2 byte/sec.
Not too much IMO.
Though I guess you'll get more packets on a faster connection because
the clients will try them first before bothering with the slow modem
users.

Nope, shouldn't matter AFAIK.

Your TTL system makes sense.
But as long as the developers rely on the old protocol to maintain
backwards compatibility there isn't much room for changes.
