Is radio-based communications technology rapidly becoming the limiting factor in our ability to explore the universe beyond the confines of our own solar system?

If that is the case, what chance do we have of finding a replacement for this slow and distance-limited method of communicating with our distant ex-solar probes?

I'd love to say tachyon-based communication but I suspect that's about as likely as FTL or transporter beams. Quantum entanglement does look promising though - at least there have been some interesting experiments with that. Very, very weird.

It looks as if Thunderf00t agrees that we're reaching the limits of exploration distances in space:

Are there any planets suitable for building a repeater array? Seems like the kind of challenge Elon Musk would be up for

I think the problem is that planets orbit at different speeds around the sun so would only be of use for a very small percentage of the time -- ie: when they were actually between the Earth and the probe itself. What's more, we can't even put a repeater satellite out there because it would also have to orbit the sun or be sucked in by its gravity.
