So we are thinking along the same lines.

In a nutshell...
Debian's equivalent of a .spec is the "debian" subdir in the source
tree, containing administrivia and a "rules" makefile; doing
"debian/rules" compiles, "debian/rules binary" compiles and packages,
"debuild" compiles, packages and checks the package for errors and
conformance to Policy.  There can be a lot more to it, but nothing the
author needs to worry about, in fact the author does not need to know
anything about Debian.

There are tools that create the debian dir and pull information from
the source tree to customize the package, it is very easy to script
so it can debianize anything thrown at it - provided the source tree
is reasonably consistent.

No, it isn't.  The authors should not need to know anything about the
final format of their module, just that they need to provide specific
pieces of information if they want to be included in the network
(imo).

Hmmm, so RPM based systems don't have a way to automatically generate
a .spec file from a source tree... that would be a must.
