I'm not opposed to going with WAMP. It's just out of everything that's stuffed into Windows, I only need a very small subset. With an imaged LAMP, I can copy and scale very easily. I guess I'd rather have 20 boxes whose CPUs were only the doing the few things I care about than all the other stuff that goes with Windows -- patches, updates, Active Directory, Kerebos, etc.

But no, I'm not ruling WAMP out. I was curious to see what kind of learning curve we're talking about moving from a windows to a LAMP environment. A couple of months ago, I downloaded a LAMP vritual appliance, but didn't have a good grasp on how to do even some very simple things.
