I work on the Partner team here at Marketo. I don't have any direct experience with PFL and ABM, but know they are doing a lot of cool things in this space and a GREAT Marketo partner. I'd be happy to put you in touch with someone there. Let me know.
I'm also going to move this conversation to Marketing Central to see if you can get a response from someone who has direct experience with PFL.
Let me know if you have any questions.
