great news man... awesome... good job!!!!!
Is it going to be open source or is it going to be a commercial product that we have to buy.

Like anything else in Windows, it's a kludge ontop of a kludge ontop of
another kludge in order to fix the original kludge. Since Windows
programs can't rely on being able to open files that other programs have
open, there would be no way to write a useful tape backup program. To
fix, they added "backup semantics". If your process has permission to
do so, it can request backup semantics which will allow it to open files
which are already open.
Of course it's this sort of thinking which is the reason why the Windows
API to open a stupid file has seven parameters and a buttload of flags
and pointers to structures which no longer work in recent versions of

The patch I'm working on will do this. I'm promising people it'll be
done by Monday (I hit a little roadblock in getting Cygwin to cooperate,
hopefully I'll still be able to finish by then). The openfile manager most
definitely uses the backup semantics flag if it can back up open files.
