not really, but my nearly thirty year old physics text book does state "If we inquire into the "mechanism" by which two electric charges exert forces upon one another, we find that, from a formal mathematical point of view, their interaction can be described in terms of the constant circulation of electromagnetic photons between them." this does correlate i believe with what you stated "Then when the ends of the strings move, macroscopically at least, photons and/or EM waves are radiated."
movement of a charge is known to "cause emission" of photons. thats another question i wonder about ie. what happens on a physical level in the event that a charge moves and a photon comes about? an electron associated with an atom in an excited state looses energy when it falls to it's ground state by "shedding" a photon. is this simply a conversion of kinetic energy into electromagnetic energy aided by a slowing charged particle ie. the electron?

yanniru, the rest of your discussion was most interesting but i must confess i'll need to study up on string theory a lot more before i'll be able to undertand it fully.
the concept you discuss with regards to symmetry and various charge natures is interesting.

regards tim
