I've been playing around with the guiminer program, it will show the statistics on any one machine for every local instance running as well as a total aggregate Hhash/s rate, so the data is available somewhere!
I just need to figure out how to access the data over the network for multiple machines and then I can setup a script to poll each machine remotely and display it all in one place for me.
Does the bitcoin client (running in -server mode) keep any statistical data at all? If so, where?
Thanks for the leads!
