A look at the PyPy 2.0 release
The useful components in a google search result would fit into a single packet.
I would like it if google's search was more like DNS in structure and brevity.
Increasing the TCP initial congestion window

One DNS provider (name.com), in addition to returning ptrs to ad sites on missing domain names, is ALSO returning completely invalid pointers to IPv6 addresses for the same:
d@cruithne:~$ host no.such.subdomain.bufferbloat.net
no.such.subdomain.bufferbloat.net has address 22.214.171.124
no.such.subdomain.bufferbloat.net has IPv6 address 1400:0:bce5:95ab:1e00:0:2800:0
I've been meaning to discuss this with them once I can summon the needed diplomacy and tact. So far, no luck.
Be careful what you wish for.

I'm still waiting for gopher 2.0 with, say, links in utf-8 text.

It works the command line and in emacs.
The latency improvement is remarkable. The S/N ratio is nice too.
Originally, it was a client/server protocol that ran over udp, I've been thinking of resurrecting the server piece, possibly using sctp, as I think latency can be further improved with a persistent connection for search.
Google's search IS so fast that in many cases the RTT for initial TCP setup dominates the entire session - I can get a 50ms response for a query located 2ms from google, and 200ms (at best) for one from Colorado.
I would certainly like more people to give the idea and tool a shot.
Gnugol also supports bing and a few other search engines - I thought what I wrote here about stackoverflow's interface, vs gnugol's to be pretty damning.
