We have a custom distro and what we do is have a 
mini-dinstall repository that we upload our packages to. 
Then we use apt pinning to give our packages priority.  Thus 
even if a newer version is uploaded to Ubuntu's repository, 
apt keeps our version installed.  Obviously, this means that 
we have to keep up to date on security related updates, but 
to date this has not been an issue.
