Microsoft Unveils Live Communications Server 2005 "Key enhancements in LCS 2005 include these:
LCS Federation (between organizations). Presence information and IM now can be extended to partners, suppliers and customers, enabling more efficient collaboration and a channel for bringing geographically dispersed people together. Two or more organizations will be able to communicate and collaborate in real time, in an encrypted, authenticated and managed environment.
Outside access solution. End users now can connect to presence and IM capabilities when they are outside the corporate network, whether working from home or on the road, or visiting customers or partners. Access is provided in a more secure and authenticated manner through the use of standard firewall ports, without requiring the establishment of a Virtual Private Network (VPN).
Improved architecture. Customers can now benefit from substantially improved reliability, availability and scalability allowing them to recover gracefully from unplanned downtime, and delivering a higher level of availability through a tiered architecture. Deeper management options and administrative tools also have been added to reduce overall management time while increasing the level of control available to the administrator."
