Only two of those are reported by Netcraft as being PLT Scheme: htpd.org and
www.htus.org.

The results for the others are:

* The site www.schemers.org is running Apache/1.3.26 (Unix) Debian GNU/Linux
on Linux.
* The site srfi.schemers.org is running Apache/1.3.9 (Unix) on AIX.
* The site scheme2002.ccs.neu.edu is running Apache/1.3.14 (Unix)
mod_perl/1.24_01 mod_ssl/2.7.1 OpenSSL/0.9.6 on Solaris.

Also, although www.htus.org reports as PLT Scheme, the site "htus.org"
reports as "running unknown on FreeBSD", because it seems to currently be
parked at Yahoo domains (http://htus.org).

So, the current census of PLT Scheme servers recognized by Netcraft is:

www.plt-scheme.org
www.htdp.org
www.htus.org

By cheating, two additional "sites" can currently be obtained from the
above: plt-scheme.org and htdp.org, since Netcraft seems to count these as
different sites, having different hostnames.  So if htus.org is changed to
point to the same PLT server as www.htus.org, the apparently magic target of
6 will have been reached.
