I see what you’re going for here and I agree that we should do whatever we can to make installing new releases easier. For all our Eclipse 2.1-based releases, we place them on our update site so you can install them through the standard Install/Update mechanism so this would suite you nicely.
Eclipse 3.0 is currently more difficult, for a number of reasons. First, we also make all our updates available on our update site, but it will really be of limited use right now. It seems that each new release of our 3.x products also support a new version of Eclipse 3.0’s M builds. To get the update, you need the new M-build which means you’ll be doing a complete installation since the M-Builds aren’t upgradable through the standard mechanisms. Adding to the problem is that the update functionality in Eclipse 3.0 is being completely rewritten and is not really usable yet and you see the delimma.
It is specifically for the ability to easily deliver updates, as well as the instability of the 3.0 M-builds, that we still strongly recommend that all production work be done using Eclipse 2.1.1 and MyEclipse 2.6.x.
