Is there such a thing as a PORTABLE LimeWire?

By definition, all Java programs, including LimeWire, are portable. Because they do not use the Win32 API directly, however, they will not work if the computer does not have a Java VM installed.

In the 'Related links' section below, you will find a link to a portable version of FrostWire. FrostWire is based on the code of LimeWire and works in the exact same way, but has additional features, like a chat room.
