I had also been assuming this was the way forward - then you could build
whatever you wanted to do there....
and if your program output the complete Encyclopaedia Brittanica at 1 or 2
characters per second in continued sections of a 550 reply, then that
would be just fine....
[and some people might consider this a good place to put a piece of
software which gave the other end a free checkout wrt to network exploits
etc - why not fragment the packets going back with a nicely broken set of
fragment offsets (the teardrop bug discussed last week on BUGTRAQ), or try
sending back a 2MB response line to see if people have their buffers
length checked (actually a set of continuation bits might well do it
anyhow). Of course I would never actually recommend such an approach :-) ]
