Spread-spectrum radio systems are not that easy to DoS, a good benefit from
the original military applications.
Trafic sniffing is something to worry with, but IPSEC is there to be used
when needed...

A 11Mbps (half-duplex) wireless LAN is capable of carrying multipoint
traffic interests of a dozen peers with up to T1 speeds traffic interest.
Those speeds were very common in south america when telecom state monopoly
was in place, so it may fit the original poster requirements.

Most wireless vendors have or will soon start shipping upgradable cards to
the 40-60 Mbps wireless standard, which may be more suitable for aggregating
long-haul connections.
