    According to Document BR68 where much of it is in a table format called the
    Schedule, from 2400-2450 MHz licensed hams can run upto 400W (26dBW) and the
    Permitted Types of Transmission include: (5th column) Morse, Telephony,
    RTTY, Data, Facsimilie, SSTV, FSTV.

    >NOTES TO SCHEDULE
    >(d) *Any modulation technique* (except for pulse emissions below 1000 MHz)
    may be used >for the types of transmission specified in the fifth column of
    the Schedule which are >defined as follows:
    >Morse : hand or automatically-sent Morse code
    >Telephony: speech, including selective calling signals
    >RTTY : radio teletype and AMTOR
    >Data* : digital codes representing numbers, text, speech, images,
    measurements, > computer programs or other Information
    authorised by the Licence
    >Facsimile: transmission of fixed or graphic images
    >SSTV : slow scan (ie, reduced bandwidth) television
    >FSTV : fast scan television.

    Reading that makes me believe using Spread Spectrum is legal in the UK under
    Amateur their rules..

    >IDENTIFICATION - 7(1)
    >(d) by the same type of transmission that is being used for the
    >communication;

    Reads basically the same here, nesting your call in the ethernet datagram
    should fullfill this.

    Hope this helps, 73' Steve
