we've heard these objections for a couple of years,
but have yet to see real problems. in most cases
people accept a local swap disk, which fixes the
whole problem and still avoid captured data on the server.
you can even have two swap disks mirrored.

today i noticed in a recent ;login: a conference summary of the 2005 Kernel
Developers Summit,
which observed that the convergence of networking and storage subsystems
``can cause problems when memory gets tight; the block layer needs to write out
pages
to free memory, but a network-based storage layer must allocate memory to
accomplish
those writes. There are things that can be done to address this problem,
but Linus Torvalds also wants to push back on the manufacturers of these
systems.
Rather than go through all this trouble to make network-based storage work,
wouldn't it be better to just install a local disk?''
