Not really. First of all, that support should have been implemented with
the rest so that it's available in lenny already. Then many options and
features rely on the fact that tar is used. So it would probably requires
addition of a supplementary abstraction/indirection.

I try to avoid depending on modules outside of perl-modules. I might
consider a patch if it's clean enough but then it will be not easy to
integrate it cleanly.

Then it will also require supplementary modifications to dak to allow .zip
and I don't know if ftpmasters would like it, you should better check this

Why would it be impossible? You can modify the patch series to integrate
whatever set of patches that you want...

You can avoid using auto-patching of course, just put your patches
somewhere else than debian/patches/.

How are patches distributed and what kind of conversions is needed?
