Public Instant Messaging Connectivity Integration
One of the most exciting and most anticipated features of Live Communications Server 2005 SP1 is the
Public Instant Messaging Connectivity (PIC) service. With PIC, LCS users have the ability to add and con-
tact users of a public network from their Microsoft Office Communicator 2005 client. These conversations
are then secured using Mutual Transport Layer Security (MTLS). Figure 1-17 shows a diagram depicting
the PIC architecture for external connectivity to public Instant Messaging applications, including Yahoo,
AOL, and MSN, over a secured MTLS connection.
