The
http://www.w3.org/TR/svg-native spec is authored by Adobe’s Sairus Patel and Apple’s Myles Maxfield. Before SVG was put into the OpenType spec, the SVG Glyphs spec was co-developed by Sairus
Given that Adobe has contributed the PS rendering code into FreeType, and are co-developing the SVG Native Viewer, I think it's likely that they'll be more than happy to work with FreeType devs and, is needed, answer questions and "make things happen" on their end. And Sairus is a great, very open-minded fellow, who, well, co-authored both OT-SVG and SVG Native, and also has once written portions of the Adobe FDK for OpenType. He is both a font guy and an SVG guy :)
