Debian Multimedia Team and Ubuntu

[Grammostola Rosea]

Hi,

I think building packages for Debian could also improve Debian 
derivatives, like Ubuntu, for multimedia  production. And Ubuntu users 
could contribute to the Debian multimedia team by maintaining packages. 
It would be nice if Debian and Ubuntu users could have some kind of 
working together to improve Debian and Ubuntu for multimedia production.

Ubuntu users could contribute to the Debian Multimedia Team to maintain 
packages, but they also want to be sure that their packages they make 
for Debian will hit Ubuntu of course.

So I was wondering:

1) how can I maintain a multimedia package for Debian and be sure that 
it hits Ubuntu (Studio) too?
2) how can I make a Ubuntu package from an Debian package?
3) how can I make an Debian package from an Ubuntu package?
4) how could we improve this 'working together'?


Thanks in advance,
