One common request with SharePoint is for a user to be able to access information when they are not connected to the network. This is not something that SharePoint really provides out of the box - apart from the ability to publish a read-only version of Contacts and Events lists to Outlook 2003.
Colligo are about to launch their Contributor product that allows you to take lists and document libraries offline, make changes to them a synchronize back to the server the next time you are connected.
Not only that, but you can download Colligo Reader for free. As the name suggests, this gives you are a read-only view of your documents and lists. Still very handy.
Colligo currently does not support threaded discussion, picture libraries, attendees, objectives or survey lists.
