Yes, but then server polls client, not in reverse. It does so probably
in some periods. However - there is no need for client-to-server
communication, if we don't actually send message, while Gorim, Express
(IOS) polling means constant flooding of server in set period of time,
e.g. each 3 sec. That sounds terrible, but there is not probably any way
around ...

Yes, it is so. But well, if company really works to allow ICQ or IRC or
some other service, because it finds it usefull, why not to do so? There
should be both ways possible, while I think that Rugby does not allow
something like that by its architecture ... I can be wrong, as I haven't
studied Rugby completly. Deferred ports, however, seem to store pairs of
index, port-objects, to check back later for the result, but on the
server side web-handler calls stop o/port, and client port is killed.
btw: does anyone here know, how does Jabber work in the principle? Is it
request broker like Rugby is, or? ....
