Comment 8 by Alex, adv. diab.

In Feynman's picture, the virtual particle that is exchanged really carries the momentum from one particle to the other.

Yes, but it's not carrying momentum because of its movement, as in the thrown ball analogy.

Also, forces can carry other things than momentum. Gluons (the mediators of the Strong Force) can carry "colour" changes.

Perhaps we should think of them as paint-balls, or dollar bills covered in ink? :)
