Meanwhile, here in the real world outside Andrew Orlowski's fantasy land, real architects like me are still successfully producing large-scale solutions using protocols like SIP, XMPP, RTP, G.711, SMTP, IMAP, HTTP, DNS, TLS, XML, LDAP and another hundred open standards..
Why should Apple's closed-system messaging automatically be assumed a success? Facetime is a failure. Not everything the Church of Steve produces turns to gold.
There appears to be conflicting information about whether or not iMessage will be XMPP based, but Apple have rocks in the head if it isn't.
