No Malaiac, this works for all.
The only change I made is calling the server by IP instead of name.
After opening the connection to the server data is send by this line:
fputs( $argyle,
	  "GET {$parts['path']}?check=" . wp_hash('187425') . " HTTP/1.0\r\n"
	. "Host: {$_SERVER['HTTP_HOST']}\r\n\r\n"
);

The line with Host tells the receiving webserver which website the
data is for. The webserver will do the rest.

For example my site has IP address: 74.50.21.205
If you do reverse lookup it will respond with direa.lunarpages.com but
if do a telnet over HTTP:

$ telnet 74.50.21.205 80
Trying 74.50.21.205...
Connected to 74.50.21.205.
Escape character is '^]'.
GET / HTTP/1.0
Host: blog.avirtualhome.com

As you see it returns my web site while if you omit the Host part:
$ telnet 74.50.21.205 80
Trying 74.50.21.205...
Connected to 74.50.21.205.
