I am not sure this overhead should be put on the server side. A place to
rsync could me transmitted to clients and they should start downloading
in the background. Then there might be a way to encode this information
in a stateless manner. For example a client could advertise his
capabilities everytime it asks for work.

I did not follow all the discussion, but why is it a good idea to ask
for tasks in advance ?
