Lightroom SDK beta tester?

Since Lightroom is part of the PhotoShop family, I figured this the correct place to ask my questions - if not, please redirect me.

I dont know if Adobe has done it in the past, but I'm interest in being a beta tester for the Lightroom SDK. So, my questions are:

1)Have they had beta testers for SDKs previously, and
2)How can I become one for Lightroom?

Any insight will be appreciated.

Thanks

Pete
