So, if I understand correctly, we're still unable to mine GRC on an headless linux rig

Have you an ETA about that ?
6) Gridcoin will measure the processes individual thread utilization, memory footprint, authenticity and send that information back to same thread that rpcmining is running on. It will not provide a higher subsidy unless all of the requirements are met, and the mining module is registered to the machines registry. Boinc Points will be part of the base algorithm soon.
Is boinc point part of the algorithm already or do we have to wait for that too ?
By the way, GRC is a GREAT idea. Imagine a coin which yield profit and benefit the science at the same time. It would be wonderful

I can't wait to test it ! We're still lacking features but you job is VERY promising guys !
We have wine-alpha available; please help us test it out if you can & see if it will mine?
