multisite configuration?

I looked through several pages of support here and didn’t see anything about multisite. Nor on the desc/faq.
I’m using fast secure form and activating it per subsite. I’m wondering what would be the best way to use/activate cfdb and if there’s a way to collect data from all subsites that use fscf but save it into one db/table. Subsites get their own db table for certain things including posts.

Thanks
