Microsoft extends the reach of Live Communications Server 2005 to Mobile Devices.
As an initial step, the Microsoft unveiled plans to deliver a new mobile Live Communications Server 2005 client, for Windows Mobile-based devices.
More details in Microsoft press-release.
If you cannot wait for that client, Gear Live reports about the eMessenger, a web-based Microsoft MSN Messenger client. The interface can of course be used with the Sony PSP Wipeout Pure Web browser hack. It is really time for Sony to release the update for the PSP that includes the web browser. It is not that convenient to use the hack.
