Just because one isn't integrated with DA (yet), doesn't mean there is no solution. I'm running a ClamAV+Exiscan+SpamBlocker setup, I used to have ClamAV+MailScanner+SpamAssassin, but prefer the exiscan setup, and the SpamBlocker plugin is very nice.
There are how-to's on setting up exiscan and mailscanner. My suggestion is do a 3rd party setup, then when jlasman releases his, you can go with that setup. jlasman already stated give him until the end of february, it's only the 13th so you've got a little time until it's released.
My 2 cents.
