Is there a Mac or Linux version?
Sorry, but there is no Mac or Linux version. AutoIt the software Portable-VirtualBox is made in only supports Windows, so there is highly unlikely that there will be support for any other operating system.
Can you make me an exception to your license?
Portable-VirtualBox is developed by several developers under a license that is an open source license, but not so suited for software it has turned out. Each developer remain copyright for his contributions but you are free to use our work according with the "Attribution-NonCommercial-ShareAlike 3.0 Unported ( http://creativecommons.org/licenses/by-nc-sa/3.0/ )" license.
If you need an exception from the license no single person can grant that to you. You would need to get an exception from every developer that has ever contributed, and that would be hard to do because we have lost contact with several of them.
