Not yet, but there is some thinking going on to make these things
possible in the future

Yes, look at the command object. It uses an ebxml message and some
commands parameters. Trace back a little and you will se how a ebxml
message is composed

The client communicating with the server is based on http. A command
object is passed to the server. So if the firewall does nothing more
than port filtering you should be fine. If it does more and block e.g.
none text/html mime times there is a problem since the mime time of this
command object is different

Again, there are some discussions going on on this issues as well.
Nothing for the near future, but keep watching this forum, or better....
join the discussion, come with good ideas :-)
