People keep citing IM as an example of something that the iPhone can'tdo, but this simply isn't true for XMPP/Jabber IM. The XMPP architecture is client-server, with a server (or cluster) per domain talking to otherdomains in a mesh - just like email. Since an XMPP client talks to therest of the network via its home server, it doesn't make any significant difference whether the client is native or web-based - just like email.
You lost me on the conclusion. The XMPP client does talk to the rest of the network via its home XMPP server. But there's no way to use XMPP from the iPhone without adding a Web server to the picture, and letting it be the XMPP client. Worse, that web server must know and cache your password. Normally, XMPP can use smart, end-to-end authentication protocols. But since the iPhone isn't speaking XMPP, only using a normal web form, those auth tokens must be sent to the intermediary. That's the real problem: while you can add Web-to-Whatever protocol adaptors to make the system perform the same functions as if the iPhone were a real computer, you have to trust those new components far more than you would any component of the old system. The new web server + XMPP client added are certainly a new component, even if they happen to run on the same hardware as the XMPP server. -Brian -- Brian Sniffen bts () alum mit edu GPG Key fingerprint DED2 61C9 3CBA E7A2 D20D F933 D379 A524 79E0 25F1 Want to verify that I sent this message?
