This data could be stored in nvram to survive reboots, kindof like the
dhcp leases file (doesn't that survive reboots?).   So far I have not
seen this as a big issue.   Is this something that others would want

Sorry about that, we've provided almost no documentation for how to run
these things.

Exclude Ports modifies the outbound firewall rules to deny any outbound
traffic destined to those ports.  It is commonly used to block outbound
SMTP traffic (port 25) so that a hotspot could not be used by spammers.

Login Timeout is the number of seconds before a user gets the splash
page again.  Most people set this to be about a day (86400 seconds)

Verbosity specifies how verbose the log file (currently
/tmp/services.out) is.  the 10 setting is for debugging only and will
quickly fill your memory, so watch out!

Currently this is a manual process.  You must edit
src/router/splish/htdocs/splash.html in the source tree and then rebuild
the firmware image.

hope this helps,
