Thanks. I have never heard of such a method to make servers safe, but
I like it! It seems to be the method of choice.

I think there must be also a way to change uid from linked-in driver
(perhaps by using setuid() function), but it doesn't look erlangish
enough to be safe.

Also there might be other methods to try (built into erlang
environment like some_mod:setuid(UID) or belonging OS like
os:cmd("magic_set_uid_command ErlPid UID")), but I know nothing of
them.
