what about letting it play virtual files so to speak. create
arbitrary regions in multiple (or the same) files and a play list
assembled from the region id's. you can simulate direct access, huge-file
handling, speedy deletes (delete first 2megs of a 100 meg file, etc), and
large undo buffers with this. all operations would be done upon a flush
or close.
