Then how will the news server know that the client is compressing data 
after the use of STARTTLS where a security layer without compression has 
been negotiated?
It cannot guess it; and it won't try all uncompression methods to see 
which one has been used.

Unless you are speaking of an update of the NNTP protocol to add a new 
compression capability (for instance with the use of a new COMPRESS 
command with possible arguments), that could be used by clients?
Well, it will require some work to specify it.  Not to speak of its 
implementation afterwards.

I bet other protocols would also need similar new specifications to 
explain how compression can be enabled.
