Referring to #24. This is what I do all day: Local Hardware locks: 20/20 Design Lectra U4ia -each dongle must be licensed individually Datacad Predator Lightwave Network Dongles: MasterCAM Lathe MasterCam Mill MasterCam Wire FlexLM: GibbsCAM Unigraphics Arc/Info Catalog A few othere that I cant remember cuz the kids are waiting to leave and are driving me batty. =) The only savior I have at work is the unlimited licenses of Autodesk and Microosft Products that require only a serial number and no other copy protection. In short, I know all about the licensing headaches of these products at my employment, and I refuse to go through it at home too.
