In effect, I believe so.  However, the compress line can also specify 
that the server do it, 'compress server best' which might be helpfull 
timewise if the client is seriously short of horsepower and the 
server is not also functioning as its own client, which is the case 
here.  I'm considering doing that with a couple of my client dle's, 
as I am seeing only sporadic bursts of data on the net when it is 
doing 'client best'.  Its only a 500mhz K6-III box.  But that might 
not be of much use if the server is also its own client as that could 
mean two such compress best's would be running at the same time on 
the server.  Still, a 2100mhz should be able to do two of them at 
about 1Ghz each I'd think.

Thinking out loud...

I agree, it could use better docs, something I think Stephan W. is 
working on from time to time, and which I'll plead guilty to not 
haveing paid sufficient attention to his efforts.
