SLAM stands for Social|Location|Annotation|Mobile. It is a Windows Mobile based application that enables lightweight, group-centric real-time communication, location awareness and photo-sharing developed by Microsoft’s Research group.

The core concept behind Slam is a ?Slam?, a group of people with whom you can exchange messages and photos. When you send a message in Slam, it is automatically sent to everyone in the group to which you sent it. For smartphone users that have the Slam client installed, their phone will buzz and they will have an indication on their phone?s home screen that there is a new message. For SMS users, they will receive the message as an SMS from the Slam server. Like smartphone users, SMS users can be members of multiple slam groups. SMS users will send / receive messages to a different phone number for each slam group they a member of.

One nice feature is the location based feature that shows the location of any member in your SLAM group for real time event co-ordination
