I don't know.  The main problem is that endings with a pawn are probably going
to be over 2 gigs, which means many systems are not going to support them.
Linux has recently added 64 bit file offsets to handle this.  NT has had it for
a while.  But many don't.  I shudder at the size.  I set up for 120 gigs on the
ftp machine.  We are approaching 40 already.  :)
