	Yes. Particularly I want to write a file with tethereal that will 
be readable with NAI's Sniffer Pro 4.0+ . Ethereal can read Sniffer 
Pro's format, so I thought there might be a sneaky way to also write it.

	Well, the current version of ethereal can read the Sniffer Pro 
format (which seams to be netxray in disguise), so I was thinking that 
if there was already a way to read it there must be some way to write it, 
but as you have pointed out this may not be the case at all.

	I don't think there was ever any documentation written ;) Its
amazing
what the ethereal people have accomplished.

	Thanks for the prompt reply.
