My colleague Richard in the UK just informed us on a very very cool new solution for the British Library :
You may like to check out the British Library rich internet application that was launched at the Vista and Office GA launch in the UK today by BillG. Rather than me explain it in depth, try it for yourself at http://ttpdownload.bl.uk and tell your friends. Some of the worlds most precious books in dynamic 3D with light specularity, flow text, audio and community functions all hosted in the browser as a click-once deployed xbap.
All feedback welcome. Hope you like it!
