It will, it's in the "planning stage" for some time now, recently i needed to make browser plugins that will work in any browser on any OS and i found the XPCOM technology used by almost all browsers except IE wich uses COM(ActiveX), XPCOM is OpenSource unlike ActiveX wich is proprietary.
This technology could be used as base to the IDE packages wich are plugins, of course it sounds simple and it is but a lot of work is needed and there are simply to few programmers to do it.
I'm one of those wich loves IDE packages and i plan to add them myself if i have some time and of course after i complete the things on my ToDo list like the plugins i was talking about
