The idea of doing something like SILO has been rattling around in my head for a while now. I'm so happy someone else got to it first. Can't wait to see it implemented: hopefully as part of an ISAPI plugin?
I would like to see a free tool which does all this stuff for me and ensures I don't have to worry about it. On top of that, it should provide the ability to 'fall back' to verbose execution mode with a querystring or cookie or something - so that amateur developers can gaze in awe at my incredible code (i.e. I can debug mixing up '>' lt and '<' gt again).
