If you aren't comfortable using a beta product in your production environment, based on what I'm hearing here, you are probably safe using Microsoft's ForeFront for Exchange 2010. You can use a trial version of that for 120 days, by which time we should have a production version of PM3.1 in our hands. Granted, you'll have to pull FFFE off and install PM when the time comes, but if you're chomping at the bit for 2010 like this, you probably won't mind that so much.
