I don't know of anyone in VA. I think JD is in PA and Guro Chuck is in NY, but the east coast is still pretty sparse. Giron Arnis Escrima does have an affiliate program (
www.bahalana.org) and some decent DVDs that GM Somera put out through Masters Magazine, but the DVDs are more like a MA seminar with training material than a look at the full philosophy of the style. Think the Larga Mano DVD is closest to the combat philosophy. The art is still Old School enough that they only share so much publicly. It's not a mystical thing so much as a trust thing.
Training in person really opens things up, but that's not an easy prospect for everyone.
As for comparison with Messer, there's a lot that looks familiar in vids like:

The stances in the vid are much higher and the footwork looks unsteady to my eye, but I can see the similarity to Giron's De Fondo style in the way that the response to an attack both neutralizes the threat and puts the defender in a superior position to counter with few effective responses. The main difference I see is that in Giron the non-weapon hand is much more involved in checking when moving forward and more likely to try to maintain range if conditions allow. So much of the system revolves around knowing when and how to close or maintain distance and what happens in the transitions.
