Sound doable - we've had previous package with the version number in the
package name, eg. qgis1.1.   That essentially all it takes.  Of course that
also requires that the files are installed into separate directories - but
the packaging scripts are already able to do that.

But it breaks the upgrade path.  But that could also be fixes by makeing the
qgis package a meta package that depends on the current version (although the
previous version would live on without being replaced).

But do we really need that?   We also have the standalone installers that
already are a snapshots of the previous versions in OSGeo4W and can be
installed in parallel to OSGeo4W.

That would also take care of the problem that older versions might need a
rebuild if something in OSGeo4W changes.
