If we want to do things like this, we need to have native tar support.
(I guess something like libtar does exists somewhere...)

Not something for 1.1.

I don't think you want to add 'new features' anymore at this stage of
the 1.1 release. If something is broken we can fix it or take it out.
If something is not there yet... let it be.

After 1.1 we should first move to the 'new kioslaves' whatever they are
and then get the whole design right first (hopefully it is already).

Cheers,
Waldo
