Right now, I am trying to figure out how/where the server side will store the drpm metadata. Other.xml.gz seems like a good place, or maybe a new drpm.xml.gz, but I am not sure how such file should be written. Should I just write code that will generate drpms, and that xml metadata file too ? Must the xml file be written according to a specific form, I only need to attach a hash to each drpm, which the clients will use to know whether using the drpm will be successful.

The first thread I'm aware of was in 1998 and involved xdelta'ing the
rpm's. Google can't locate it so I'm betting it was on contrib-list
(whose archives have disappeared from redhat.com)
Some of the more recent discussions::

... and google knows of others as well. Try::
