has any thought been put into the idea of users that run multiple versions of blender and intermingling of files?

i have 2.2.1, 2.49.2b, 2.58.0, 2.6.0 and will have 2.61 asap and all of the file co-mongle from the 2.5 series to the 2.6

i abhore poser and find studio to be TOOOOO limited to even open most times  so being able to share prerigged models would be a godsend for me and might even tickle some freebie-junkies as well
