Colligo for SharePoint has gone into beta 2. Colligo is an offline solution for SharePoint and will be very useful for some cases. When you are interested in these kind of solutions, take a look at Organice as well.

“The key features of Colligo for SharePoint Version 1.0 are:
- A rich offline client that emulates the functions of SharePoint team spaces. The client enables users to download, create, organize, view, edit and save content on their laptop much like they can on a SharePoint server. Colligo for SharePoint 1.0 is tightly coupled with Microsoft Office® 2003
- Enforcement of SharePoint authentication, permissions and security. Users can only access sites and create, view, edit and delete content that the site administrator has authorized.
- Two-way synchronization of SharePoint document libraries and lists, including links, announcements, contacts and tasks. One important note here: Colligo for SharePoint offers robust synchronization conflict resolution that eliminates the need for a user to “check out”, and hence tie up, content in a team space when they go offline. This enables teams to work on the same item offline and then synchronize later.
- Support for custom properties (metadata) and the ability to view, edit and synchronize changes to properties. Properties are used to manage such things as document approval processes.
- Support for custom SharePoint views – Colligo for SharePoint enables users to view list and document library items using custom views downloaded from the SharePoint server. The ability to organize content through custom views is a key feature used extensively by SharePoint site designers to simplify and personalize the presentation of information.
The second beta of Colligo for SharePoint is available now and the final product will be released in early April 2006.”
