    Adrien,

    You should investigate using wireless ethernet (802.11b). Several of
    the 802.11b channels are in the Amateur spectrum. Also, the equipment
    is widely available and quite afordable. By utilizing yagi or parabolic
    antennas and good transcievers, you should be able to achieve a 15 mile
    distance while maintaining at least 1mbps or better.

    Of course, one of the drawbacks is that 802.11b requires nearly a
    line-of-site path as 2ghz signals are easily reflected or absorbed by
    obstructions.

    Hope this helps!
