Hi. We currently using VPC on Windows to create virtual development configurations on the same comptuer. I've messed around with Parallels on the Mac and the fact that it is also available under Windows is very interesting as we could potentially transfer virtual machines between our laptops and desktops. A nice enhancement would be if you could convert VPC virtual machines into Parallels virtual machines as this would save many hours installing and re-configuring environments. Regards, Kevin Gale
