import -k, -W options, etc.  there are different ways of getting this 
information - it's often a negotiation between the client and server. 
In normal circumstances cvswrappers is send back and forth between 
client and server and both sides merge each others' ideas of binary 
files (with the client normally taking precedence).

Not my idea.. Kopt predates cvsnt by some years and is a standard part 
of the protocol... it's not likely to change in the forseeable future.

That's not possible - they're identical (in fact the server detects the 
-k and skips over it).  I suspect something else in your environment is 
changing. Kopt -kb is the normal way of sending it & is how cvsnt 
clients send it.
