CommonFiles Directory Structure (GPG, Java, etc)
As a part of the directory standardization, I'm thinking about adding a CommonFiles directory. This would be handy for binaries that are shared among multiple applications. GTK+ would be an obvious example (used by Gaim and GIMP). Java would be another candidate for the future.
In adding on to the proposed directory structure, we'd get:
\ (Drive Root) - Documents - Music - Pictures - Videos - PortableApps - CommonFiles - GTK - FirefoxPortable (etc) - GaimPortable (etc ...
As an example, the Gaim launcher, if it didn't find GTK in the internal directory, would check the PortableApps\CommonFiles\GTK directory.
