[jQuery] Is using jQuery and jQuery (2, 3, 4, n versions of jQuery on the same context) possible?

[[EMAIL PROTECTED]]

Using jQuery with other libraries is easy:

http://docs.jquery.com/Using_jQuery_with_Other_Libraries

What I'd like to do is do inject jQuery in pages where jQuery already
might exists and even might exist in some other version. Is there a
way to do this safely or do I need to rename the main object? Any
Ideas?
