Portable ATutor LMS (already exists)

It already exists, and its open source, a version of the ATutor Learning Content Managements system that runs from a USB stick on a Windows system. Normally used over a network, this version of ATutor is handy for learning content developers, allowing them to carry the system and its authoring and packaging tools with them.

This particular version is Spanish, but many different language packs are available, if someone wanted to create an English version, for instance. Once installed on a stick, language packs can be downloaded and installed, or if conected to a network, imported directory into the system.
