So i'm going to do some assuming and make some suggestions. Assuming a full package build is normally just pushed out for distribution, this would cause much unneeded bandwidth usage among all of the mirror sites. Wouldn't it be just better to maybe keep a record of the fingerprint of a port and if it matched from the last build not send it out to the mirrors so that only things that have been updated get pushed out? The only problem with this method is that it would slow down the build system a bit while it checks the files. Or maybe instead of just blindly building the entire collection all the time, keep a database of the versions that have been built and only build the ones that change. There would have to be some extra checking in there too to make sure that all dependacys affected by a version change of any port also get rebuilt, but that method would probably work better as the build system wouldn't have to work as hard all the time to churn out packages for ports that rarely change. And then just do a full build from time to time to double check everything.
