I've added the modalias to the virtualbox package header which makes
the "Additiontal Drivers" application suggest the package.
So I guess I'm the right person to talk to. :-)
I'm not sure who else from the Ubuntu project is interested in this
discussion. Maybe Martin Pitt who maintains the "Additiontal Drivers"
software (aka jockey ).

It might be possible to detect the host VirtualBox version and only
advertise the additions package if both are from the same major release.
Of course this wouldn't cover the case where the VirtualBox host is

I currently maintain a PPA  where I upload backports of the virtualbox
package to supported Ubuntu version (currently all except 8.04 aka hardy).
I don't test these packages much but they have proven to be pretty stable
in the past.
The official way to provide updated software for released Ubuntu
versions is through the backports repository.
The policy for that repository however requires that someone actually
tests the package on the old Ubuntu release.
Sadly at the moment the backports repository isn't integrated into the
GUI package managers. So you have to execute
"sudo apt-get install -t natty-backports virtualbox-guest-utils"
to get the latest version.
