No. By design, the snapshot contains NO data which can be found in a mapped file on disk. The snapshot uses a form of run-length encoding which describes the regions of memory which haven't changed; those regions will be restored from the original file on disk. Only modified/new data is stored in the snapshot. It's a streaming format, not page-by-page. This is why I'm unsure whether the snapshot is a derived work. By design, it will NEVER contain any text/data from the original binary. The snapshots do contain the MD5 sums of the original binary files, however. Is an MD5 sum considered a derived work (I highly doubt this)? Thanks again, Scott -- license-discuss archive is at http://crynwr.com/cgi-bin/ezmlm-cgi?3
