It seems to me this is a case where GEO would help.  Deploying a few
really BIG guidable antenna arrays in geosynchronous orbit, parked over
dedicated ground stations, would allow tracking and commanding probes
all over the solar system without usurping valuable observatory time.

Such big antennae might in principle be useful for radio astronomy too,
but in practice you'd only need to build the horns for the bands space
probes use, and image resolving ability would not be a priority.  This
should remove a lot of the lavish expense and operational headaches
that would attend an full-fledged orbiting radio telescope.
