Actually this approach could be interresting, but it cannot be just a filter
programm. What would be needed is a kind of file access daemon, which has full
access to the physical representation, while receiving read/write/seek/...
requests from the user tasks.
To be practical, it should be possible to use this dynamically, this means
the file access daemon should not be bound into the kernel.
Concerning the implementation of this kind of stuff I cannot volunteer out of
a quite simple reason. I am a linux newbee too. My work with the kernel has
been restricted to (cd /linux; make config; make dep; make all)-like stuff.
So what I looking for is any help with linux. You know I have been programming
C for 7 years, but under DOS/Windows.
Should anybody have direction for where to find anything about the kernel,
please e-mail me.
