Can I make a two station ethernet by connecting up two cards aui ports in 
"null modem" fashion.  I have looked at the spec and see no reason I can't.  
Can someone enlighten me?

Is it so bad ? As I understand it, we can use whatever (publicly documented)
encoding scheme and modulation method we choose as long as the transmission
is identified with a CW ident. The loss in bandwidth due to a 5-second
transmission every 15 minutes is not great, and as a result we have no
mandatory requirement to use AX.25. Some modulation schemes might even
allow simultaneous transmission of CW ident and data, or an appropriate
protocol might permit the synchronisation of all CW idents within a given area.

This permits us to experiment (after all that's the object of the hobby
in this country - 'self training') , and an innocent victim of breakthrough 
to identify the cause. Seems a pretty good tradeoff to me. It apparently
also means that the RA considers monitoring of transmission content as very
much less important than identifying a source of interference - a very
reasonable position. 

What other ident laws are around ? I have the impression that australia
has no CW ident but is limited to AX.25, and the US can do either - is
that correct ?
