Hi jameless!
I wanted to use this utility on my server, but my host doesn't allow the sockets extension. They do allow the SteamTools extension though, so I modified the original to use SteamTools rather than Sockets. I've attached the source, hope it can help someone other than me!
Edit: To compile this you will need the SteamTools.inc, I've attached a compiled version since the built in one doesn't seem able to compile.
