Work in progress covers a datasource that has an API for configuring sorting, paging and filtering, and an SPI for implementing different remote source (e.g. Flickr or Netflix API). There's also an implementation of a local datasource, which uses an array of existing data.
See also Grid-ObservableData for investigation of integration of datasource (sorting paging and filtering) and Grid with "observable data". It includes a modified version of grid.html demo from below.
