why not supply the credentials to lynx like so (in the programming
language of champions 'P-e-r-l')

my $lynx_cmd  = $lynx_path . ' -auth=' . $pwstring . q( -dump -nolist
-width=132 'http://localhost/nagios/cgi-bin/avail.cgi) ?
   $lynx_cmd .= '?' . eval($qs) . q(') ;
    my @avail_rep = `$lynx_cmd` ;

where $qs is the actual set of name value pairs your browser would
append to the cgi path and $pwstring is 'User_Foo:Foo_password'.

But this is only suitable for dumping the content if you want to mail
it periodically or view in glorious mononchrome.

This approach is more colourful but still doesn't allow for the 

- initial drag in of the CSSs or

- anything alse the report includes

However as long as you start by browsing a Nag page, this looks like the
real thing.

   my $avail_cgi = '/usr/local/nagios/sbin/avail.cgi' ;
    $ENV{'REQUEST_METHOD'} = 'GET' ;
    $ENV{'REMOTE_USER'}    = 'foo' ;
    $ENV{'QUERY_STRING'} = eval $qs ;
    my @html = `$avail_cgi` ;
    print @html ;

This is within a Perl (CGI module) script. It depends heavily on the
Nagios::Config module on CPAN to parse the service and host names from
the Nag config so they can be put in chooser boxes to generate the query
string ($qs above).

Please, I mention this because I thought it could help you along
only. The script I use is unfit for human consumption so I would rather
not share it.

If you can interest someone in providing a 'management fulfilling
experience' in connecting Nag to Cry&*_l R(&#@rts (this is a family
program) or E!!el, you will do the project a great favour and send
Tivoli share prices tumbling.
