Bamboo's MashPoint REST will allow you to create client side "gadgets" that requires no assemblies to be deployed on the server and still have access to the whole SharePoint object model as well as your LOB systems through the REST api. These scenarios will be more and more popular as we move to hosted solutions and cloud based computing. The API supports multiple standard representations; out of the box we support XHTML, ATOM+XML (Both ADO.NET Data Services and GData) and JSON. For specific resources we also include support for vCard and iCalendar. The MashPoint REST stack is fully extensible so you can add your own serializers and mappers (I'll describe this in a later post) and you can expect Bamboo and our partners to release more add-ons in the future.

Install MashPoint REST

Download the installer. Extract the zip file to a folder on your SharePoint web front end server and start setup.bat then click install.
Next you will have to select the WebApplications where you want the REST API installed, here we select Central Admin, our BSSP and the "default SharePoint web site". You can also select the "Automatically activate features" so you don't have to manually activate the features.

Full details on MashPoint REST are available in the MashPoint feature area. Please use MashPoint REST forum for feedbacks and suggestions.
