This looks really exciting! Do you plan to add a way so that people can submit performance data? I.e., if I set up my own test box and want to submit a result once a week for that, will there be a way for me to get set up with a username/password, submit configuration information, and then automatically submit test result datapoints? Especially if I can specify both the X and Y coordinates so that I can backdate results should I go back and generate test results for old kernels? Very neat, and I look forward to seein gmore!
