Make it pluggable?

What do you think about making this module pluggable? You already have the specifics of integration pretty isolated so it looks like it would be pretty easy.

This little module looks to be exactly what I wanted, but it looks like the service you integrated with doesn't check against known spamtraps or have some snazzy features that datavalidation.com or some other fancy schmancy new ones have.

Would you accept patches to that end?
