googleのインスタント・メッセンジャーはjabberベースか？

googleのメール・サービスの次はインスタント・メッセンジャーと予想されていたが、具体的に予想したものがjoogle。joogleはオープン・ソースのjabberプロトコルを採用していてオーディオ・チャットではskypeやichatとの互換があるとされる。

An important feature of Joogle would have to be contact list portability and file transfer behind NAT, neither of which Jabber can really provide. Thus, Google could implement such features in their own client, which would also display a text ad in the contact list.
And it would work, even if users could choose to use a different Jabber client that didn't display an ad and was even more customisable, for the same reason more AIM users don't use Gaim.
What else would it need? Audio chats are important in modern IMing, so this is a must. Optimally, Joogle's audio chats would be compatible with other VoIP software, like Skype and iChat. Also, since AIM maintains some public chatrooms, Google would be obligated to provide these as well. The difference? AIM's are totally unmoderated, which allows bots to clog the rooms (there are often ten bots per user in these rooms). Google could moderate their own rooms, filtering out the constant droning of COME SEE MY WEBCAM, enabling users to carry on, at least, semi-intelligent conversations.
