I really hope you will add a feature that I really like about Simplemining.net - namely that I don't have to add a mining rig to the web interface - simply putting in my email address in the rig config is enough and the rig will show up on the web interface. In your case, I guess it would be the access/token. Then I can rename it on your web interface etc.
Would be nicer than having to manually add each rig as I add them.
I would also be interested in testing the minerstat OS when it is available to test.
