Has anyone seen this?

Involves using the Burrows-Wheeler transform and suffix arrays.

Seems interesting. Not sure about licensing/patent issues though. Still, a

Yes, I've read it and have corresponded with Paolo Ferragina.
Most interesting is  String B-Tree data structure

I hope we could try something in next year, this year we're too busy.
