So what you are saying is that Serial is the way to go with this ?

12-20 servos sounds like your project is out of control, but that's your
deal.

this is what I'm using, with a 600MHz verdex.  I connect it to /dev/ttyS1
http://www.pololu.com/products/pololu/0207/

you can slave several of them together.  

They also sell these:
http://www.pololu.com/products/pololu/0240/

but it's larger.  Of course, if you have an airframe that needs/has 20
servos, 
I'm thinking weight and size of the board are less of an issue.
