It's nice to see this work taking Doppio into new places. For an overview of Doppio, BrowserFS and the DoppioJVM, here's a video presentation mostly based on a talk given by John Vilk at PLDI 2014. Unfortunately, there's no audio, but the slides should be easy enough to follow.
FIXED - forget this video, watch John deliver it at Microsoft Research! http://research.microsoft.com/apps/video/default.aspx?id=238...
