When I looked at the problem, the biggest slowdown was opening a new 
connection for each patch (each patch is stored in an individual file).  
If you want to make things fast, then I would start with transferring 
all patches consecutively instead of separately.  (I don't know how 
http currently transfers files; with scp, it used to be the case that 
they are all transferred separately.)

Given current network speeds, and given a large amount of main memory, 
applying patches locally might not be that much slower that 
transferring a working directory.

One could store tarred, gzipped snapshots of the working directory in a 
repository upon user request and have "darcs get" look for these.
