I have the IIS server still running. I can do the testing on that to get the BRK stuff up and running. After looking at the readme files it should be pretty straight forward. I downloaded the 4.0.6 version. Our BES isn't at that level yet though so I didn't want to start testing this stuff out on our live BES (although everything else I test is against the live BES). There was talk last week that they might upgrade it to 4.1.3 so who knows.
As for my linux server, if I can get all the functions I want working I will move the phpberrystats to the IIS server. It sounds like I am the only one running on Linux anyway. I can always mess with the ssh stuff here when I get bored
