Look at /etc/fstab, and consider the "ro" & "noatime" options.

Certainly. It would be a very good idea to configure the system with more
than enough physical RAM, and to take some care selecting the software being
run on the system.
[ If you stick to small, simple C programs like natd, dhcpd, etc, you should
be fine. Try to avoid complex systems and scripting languages like Perl-- for
example, trying to do SMTP + SpamAssassin + amavis + antivirus on a Compact
Flash-based host would be a bad idea. ]
