Again it's a money issue. To get more than 4GB, we'd have to then also switch to windows 2003 server enterprise edition...another $1500+. The only program that would support more than 2GB is this software that we're going to demo. Seemed silly to spend that much extra (not only the extra on the OS, but the extra RAM as well) for only one program that we'll very possibly not buy. If we do go ahead and buy that software and use it a lot, we can always switch to the server OS and add more RAM.
