you can update your httpd.conf to vary the port number based on
who is starting the thing. this gives you something like:
<perl>
...
%portlist = qw( jow 8081 bloe 8082 john 8083 doe 8084 );
$Port = $portlist{$ENV{LOGNAME}} or die "no port for $ENV{$LOGNAME}";
to check out a new version just bounce your copy of the
server and keep going. normal cycle looks something like
cvs -q update -d;
bounce;
try it, edit thing, keep going. if you reach a point where
something works use cvs commit.
