I have come up with a temporary solution, which was to create my own basic API that would allow some functionality while new routes are sought.
I personally use this API for my SimpleXBL application, and it has yet to fail me. It allows me to easily update the data harvester as necessary without having to make a new release, and also allows me to have more control over who has access to my application (license control). But I do have a public API that I just released the other day. More information can be found here: http://www.jblaze.net/2011/01/26/xbox-live-gamercard-api/.
If you are interested, awesome! If not, that's cool too. I just figured I'd post it here in case anyone else develops apps for Xbox LIVE and was wondering what to do.
