Yes, it is delivered to userland.  Jabber uses XML over the network, and 
whitespace between XML fragment boundaries does not harm the connection 
(technically, it counts as CDATA, but it is unused in this case). CenterICQ's 
parser simply eats the spaces.

So the result is: Yes, clients do get the space, but they do nothing with the 
space, and they are not supposed to respond with anything either.  The 
purpose of the space is simply to act as a "keep-alive" so that routers won't 
drop the TCP connection due to inactivity.

Are we done with this topic, please?? :)
