Even better than rebroadcasting is Forward Error Correction[1]. It's the basis of pretty much all modern radio based telecommuncation protocols(WiFi/3G/LTE/etc). Basic FEC can go a long way, esp if your packet sizes are large, latency is high or you have a lot of channel congestion. [edit] To give you an idea how awesome FEC can be quite a few ham operators do EME(Earth->Moon->Earth) contacts via JT65 with FEC[2].
