Multiple versions of the same extension

[arch]

Hello,
I wonder if it is possible to have multiple versions of the same extension. To have them installed but have an option to enable/disable versions so only one version gets to be active?

Which extension did you have in mind? normally an install of a later version overwrites the earlier. Off the top of my head: a possible way to do this might be to install OpenOffice for a specific user, not "for all users". Do this repeatedly for different users and install the extension versions for specific users.
