Transports
Transports (also called Gateways or Agents) are
the the connections from the Jabber server to other third-party
Instant Messaging systems. Transports are what makes Jabber
very powerful, but they are also a source of great confusion for
new users.
The main thing to remember is that your software
needs to educate your users that even though they need to configure
transports though the Jabber software, usually they are relying
of a service that is out of the control of the Jabber server administrator.
Users need a basic outline of how transports work to gain an understanding
of why they may not appear to work as they believe they should.
I would suggest the best approach for each transport
would be to include a link to a webpage that explains exactly what
each transport does, and how to configure it. This way you
can update the webpage without having to alter your client in any
way. It would also be useful to include a web based form where
the user can register for the third-party service if they do not
already have an account. For example, if they wanted to use
the ICQ transport, rather than having to download the ICQ client,
install it, create and account and remove the software from their
computer again, it would make sense for them to be able to fill
out a form on your webpage that registers them, and returns their
new ICQ number and instructions on how to configure the ICQ Transport
in your client.
Some services like MSN Messenger let you register
online without downloading the client software, so in that case,
some instructions and a link to the MSN site should suffice.
