He found out traces of new features like colored labels, ability to remove threads from conversation and jabber transport. For those, who don’t know about jabber transports, it’s a way to connect and talk with people from other IM networks like Yahoo, MSN and AOL by converting instant messages into jabber format (GTalk works on jabber protocol, remember?).
I’ve been using third transport servers for several months now, and it requires some tricks to configure (more details here). But going through third party transport sever isn’t favorable to everyone, and that’s where Google’s appeal lies. If Google implemented transport severs and provide an easy way to connect with other IM networks, it would be awesome for everyone.
Gmail 2.0′s new contact manager allows you to add multiple messenger IDs. This gives me a strong feeling that jabber transport is really going to come sooner or later.
