It is hard for the DIPC development team to prepare the patches for the
new kernels.

DIPC changes some standard UNIX mechanisms (System V IPC), in a _very_
compatible way, to do its work.

Depends on your definition of clustering. Windows NT has "clustering", but
it is more about fault tolerance. A page-based distributed shared memory
system is really hard to find on commercial operating systems.

I think DIPC is a very useful addition to Linux, and it would be better for
it to get into the standard kernels as soon as possible. We have been
tracking Linux kernel releases for about two years (DIPC has been usable
right from its first "alpha" release), and have been forced to adapt DIPC's
kernel patches to the changes people make there. I and other people working
on DIPC can not continue doing so for ever.
