With the separate instances, ColdFusion itself would operate within their respective Virtual Machines, each with it's own memory allocation independent of the other. That being said, the DLL is a Windows library, operating within the OS memory space. I don't think it really can be separated, unless you were running CF inside of Virtual servers (VMWare type setup), where each virtual server essentially would have it's own independent OS. I could be wrong on this, but I think that's how it would have to work. Dave Watts my have more experience in this type of arena...
