There's a lot more back-and-forth than before. Jelena Jensen did some solo and g/g scenes in the last few years. Brea Bennett did some scenes a few years back. Puma Swede has done a few for Denys and for Clara G, there are others that just don't come to mind. Lots of Ameri-whores are in shoots with "sensual porn" sites like X-Art and Nubiles, not sure where that is produced.

As for the Euro whores coming over here, I can think of Sandra Shine, Sylvia Saint, Anita Dark, Sharon Pink, Eufrat, Eve Angel, Donna Doll.

Admittedly, it's mostly solo, g/g and foot fetish type things. I imagine Euro producers are leery of the Ameriwhores after all the HIV scares and other problems, plus they have a large enough talent pool to choose from.
