CRM notifications accelerator allows you to expose CRM business data by creating Really Simple Syndication (RSS) feeds.
Users can subscribe to any saved views within CRM as a feed. This allows you to have a channel where you pull information instead of being pushed to you from the server. These RSS feeds accessible via a variety of RSS readers including Outlook, Mobile phone, 3rd Party Readers, etc. It is also worth noting that this capability can be used to easily create Vista Gadget for CRM by using the generic RSS gadget that Windows Vista ships with.
This is just a tip of iceberg on how RSS can be used with Microsoft Dynamics CRM. Since the accelerator ships with the source code as well, developers can further extend this or create new and interesting applications based on RSS & CRM.
