Sounds overly complicated...
What about a much simpler solution where the miner has a CPU in a well
connected data center. Say, Amsterdam.
He runs bitcoind on there and he, in China or such, connects to it over RPC
(and ssl) to get a "block 000f00" accepted signal. Which would be 100 bytes or
The miner continues to use his current setup, but with actual validation of
the blocks to completely eliminate the risk of mining on orphaned blocks and
at the same time remove most of the cost of larger-than-average bandwidth in
A slightly more complicated solution is needed to allow the miner to only send
the headers to the bitcoind instance. So he only sends a couple of kb and his
datacenter machine does the actual propagation.
If the risk of duplication becomes an issue, setup multiple propagating nodes
on different sides of the world.
Bottom line for me is that most of the innovation for making stuff better for
miners should be done in miners-specific software. Not in end-user software
