On Tuesday we announced the release to manufacturing of Communicator Web Access.  There is more information here on CWA but in a nutshell think of it as web based client for LCS, allowing users to gain access to the presence information within LCS on anything with a browser.

I have been using this for quite some time and it looks very similar to Office Communicator 2005 and at a quick glance its hard to tell which is which. 

Most important of all is that its free ! There is no extra cost to use this as long as you have paid for the CALs already.
