just fyi in practice i've found keeping a local copy of jquery minified and delivering it over apache with an expires date of access plus 1 year and using cachebusting filename sequentials will not only allow you to use the none namespace clashing version of jquery, but you'll probably see better performance doing it that way than from alot of people depending on what version you use and they have cached having to establish an https connection to grab it off of googles cdn.

prepare for the theme to register and load jquery as well so cover all your bases or it wont work, the order in the stack that your hook appears has alot to do with creating a hookable function that works and one that doesnt. :D
