Good point.

The "available for download click-packages" scope I'm working on is
the one that talks to the repo webservices and knows the compressed
size of the package.

Perhaps we should also make the "installed" size available on the
webservices, so we can prevent download when there's not enough space
for (temporary compressed package + uncompressed files).
Post-installation the actual package file and the old version can be
removed, but I think we should not remove the old one until after the
installation is successful.
