Don't even bother trying to "swipe" the datastore ancestor class from PFC. That's a rabbit-hole you don't want to fall down. With PFC, you're either taking the whole thing or you're not using it at all.
I remember trying to extract certain classes from PFC for use in a 3-tier PB client (PB -> EAS -> MSSQL), and found that there was one class that used an in-line SQL query - forcing you into a 2-tier client/server architecture whether you wanted it or not...
