just FYI: I've added a basic soa_vector to LibFlatArray's trunk[1].
It's not perfect, but allows basic usage and particle callbacks (see
test[2]). I'm looking forward to benchmarking that code. :-)

Yeah, macros are poor, but I wanted an interface where members have
sensible names (as opposed to first, second...) Not much options
without reflection.
