Thanks for the suggestions! David: Option 2 is nice for me because it means I can change whatever I want, but I'm just worried that released products like the app server that use a specific runtime version can be re-retroed because they are already released to our customers. So projects that depend on a particular app server version are stuck with it's retro runtime version, and can't take advantage of new features. Jason: I think this is a really good idea, and I don't think it would be that hard to implement. I'll have to look into it a little more, but maybe this is the best option for now.
