My company, a small consulting firm, has several IDL/ENVI licenses, that all use a USB 'donegal' (sp?) as a license manager/server. At the present, we cannot readily afford to upgrade or purchase a new license. I wanted to know, is it possible to install our current version of IDL and ENVI (7.0 and 4.5, respectively) on a Linux machine, and use the same license handling? I'd be most helpful to know if this is possible.
