Many of us put our unfinished (ie unbeta'd) missions up on Google Docs, because it's free and you can control exactly who can see and edit and make comments. All it takes is signing up for an account, and has all the tools you need for beta reading.
Also, a it is sometimes beneficial to have a beta who specifically doesn't know the continuum, so they can point out the in-jokes that you understand but that other people might not so that you can clarify them, which is especially helpful if you work in a small continuum (like, say, I'm currently working on a mission in the Brother Cadfael continuum, which at last count only one other person in the PPC knew about).
/my two cents.
