For a start, we could just cache the uncompressed image. Yes, 
performance would be worse, but maybe not by much because images 
generally also get cached in browsers. Performance testing would be 
useful. (aside: I have been playing with JMeter this weekend, and my 
problem is how to throttle 1G Ethernet down to simulate 56K modems. Any 
idea how to do this on Linux without getting bursty traffic? )

Again, performance might not change much, and 'easy' is good in my books.

More about SPDY at:
http://www.eecis.udel.edu/~leighton/SPDY.html
Google's index page (with links to experimental server code in Java, 
Python, and others):
http://www.chromium.org/spdy
And their server code in C++: ("The flip server is a fully implemented 
SPDY server or SPDY-to-HTTP gateway.  Full source is available")
http://src.chromium.org/viewvc/chrome/trunk/src/net/tools/flip_server/

Research to improve response times in high latency Internet browsing 
environments using SCTP:
http://www.eecis.udel.edu/~nataraja/papers/nsdr2008.pdf
Problem: SCTP won't work with NAT?
Problem: only half of the ISP's allow SCTP ?
