Errrrrmmmm... the TVC system is available *now.* However, the
likelihood of another 5-segment test by the end of 2006 is... really
low. Much less a *flight.*



How hard could it be to insert an additional segment in an SRB?


Oh, that'd be easy. You could splice ina *dozen* more segments if you wanted. It'd jsut blow itself to hell, of course.

Is there any reason to change the propellant configuration from the one used for the shuttle?

Yup. The ETM-3 5 segment motor was pretty much just a spliced regular RSRM, but witha modified nozzle; it worked, but the thrust/tiem trace was not quite what you'd want for a launch vehicle. That needs to be tailored for the vehicle in question.
