Not to be rude, but often a large portion of code complexity comes from the last bits and pieces, that get left till last because they are hard to implement.

So to sum up the apparent answers.

No, there isn't yet something that does what you want. Email:: should be close. I'm sure they'd appreciate your code to help finish off the set of Email:: module.
