kn_from and kn_to

A question or 2 on kn_from and kn_to -

The pubsub protocol document says that "/what/chat, /what/ÁãÃÈ, /what/ºyüµ 
and http://foo/mod_pubsub/cgi-bin/pubsub.cgi/what/chat.  are all valid 
kn_to values, but the implementations all prepend the mps server url to the 
value before setting it if the value does not have a scheme part.

So, should the client implementation ensure that the kn_from and kn_to 
values are always absolute URL's, converting relative URI's to an absolute 
URL on the connected mps server ?

Should I update the doco to say that?

If I specify a url of any valid server process in kn_to (e.g. 
http://example.com/cgi-bin/processEvent.cgi) when issuing a route command, 
will the mps server then send all the events directly to that url for 
processing w/o requiring a mps client ?

What is the use case for being able to post a single event to an arbitrary 
url, i.e. setting the kn_to of a notify command to point to a non-mps server?
