Currently, when a security fix is released it is done for 10.3 and 10.2, usually in both server and client formats. With the release of 10.4, that will make 3 vOSs (with two versions each) to support with security fixes. Double that with the addition of the "Combo" updaters. I wonder how much longer Apple will be supporting 10.2 after Tiger is released with security updates. It would be nice to have a universal updater that can sniff out version and type and would apply the correct updates. Right now I can imagine Version Tracker being taken over with 12 different updates all released within a day or so of each other.
