I wonder what kind of results one would get in latency and performance in general if a platform like the pmp450i 900 had a customized firmware for licensed channel sizes, ptp only, and designed for use with only high gain directional antennas (such as a pair of very large Yagis in both polarities, or a pair of 6' 900MHz grid dishes).
