Within our solar system (which is itty-bitty), there is really no theoretical limit to what we can send or receive. Bandwith is pretty high on modern satellites and probes and our only really limiting factor is latency, which doesn't matter so much when the probes can store data locally and slowly send it to you over time. NASA is currently experimenting with the LCRD[1] project for laser-based communications which have a downlink of 622mbps.
