A fairly productive meeting with Sequence has moved the snippets idea forward. The underlying search software we use has an auto-snippet function - which is a good start. So Sequence will create a testing system to demonstrate how it would work in reality. Assuming that's good we still need to decide how to display it. Do we take up screen 'real estate' and display it like Google? Alternatively, we only display it via a roll-over function?
The other snippet function was the ability to grab the documents conclusions; where they exist. This seems 'do-able'.
Assuming things go smoothly we should have something to rollout by March.
