I'd like to suggest a Jitterbit VMWare appliance be built. I have recently begun using VMWare and would build one myself if I had the utility (I just use the freebie VMWare) and technical knowledge of VMWare and Jitterbit.
Since Jitterbit can run on linux and the other supporting components are all open source - this could be done for very low co$t. Well, at least I understand the appliance builder license fee is pretty low...and, of course, there is a price to be put on time. I am fairly certain that the end result would be more exposure for jitterbit...hey - the beauty of the appliance is that it's all preconfigured - no massive install/configuration for the curious. The user experience would be:
1. Dowload Jitterbit appliance.
2. Run appliance.
3. See Jitterbit in action with some pre-configured operations.
4. Run virtual jitterbit server in production?
I bet there are people in the community with the requisite skillset. I'm probably not one....but, hey, I'd do documentation for it.
