Some further comfort. The inventor of the non-scanning electron method says it's probably going to be 10 years to the first production units and 20 to widespead use. Actually, he also uses a mask but of a scattering type -- the electrons are scattered rather than absorbed as in photomasks. This prevents the thermally induced dimensional distortion that occur with electron masks that absorb very high energy electrons. That's why electrons could not be used with masks before his invention. Of course, it could happen sooner if companies like Intel throw some big bucks at the idea. As far as I know, however, Intel likes deep UV exposure of wafers through photomasks for the foreseeable future.
