If there was a way to get a user's custom keybindings on all operating systems for a large majority of applications, I would surely do it. Writing configuration parser's for each application+OS pair is not feasible, and would not work for all applications. However, I think, in practice, you will find that the custom collections are a nice solution to this problem. I use a lot of custom bindings myself. Having the lookup show both my custom binding and the default binding is actually very nice to understand your custom bindings and find combinations where you might be better of with the default.
