The only thing we need to know in JEP-0045 is the maximum URI length,
and that seems to be set already. The rest could be left to the
implementation, couldn't it? Besides, it's easy to recommend a wide
hierarchy instead of a deep one. We think we would have to really
provoke to even come close to 256 characters. Try it yourself.
If a server would come close to having too long URIs then one solution
for the implementors would be to use shortcuts to jump to other servers.
A bit like symbolic links between different file systems. That system
seems to work fine with the web and ftp. Using links could also tie
large numbers of conferences together into one chat environment, like
IRC networks. But links are matters for the implementation.

So there's currently no limitation other than the maximum URI length to
be considered? Even a cow is allowed to play as long as it stays within
the fences... That's cool.

Sorry, but i forgot... In jabber at c.j.o we call it a row to differentiate
from hierarchies. What would you call a one-dimensional collection of
rooms? A corridor?

When interacting with a chat system such as IRC or conferences, we tend
to think that we are talking to a room when in fact we are talking to
the server controlling the room. Although we have two ways of
interacting with IRC (rooms and servers), it's is in fact the server
that answers in both cases. The same can be said about the hiearchical
jabber conference server that we are working on. We probably need two
ways of talking to the conference, but we don't have to decide how in
We see no need to hinder the progress only because of one word. The
current scope applies (and works well) if we believe "room" to mean
"chat system". We can live with that.
