Here are the current OP webmaps as they stand (sorry for the delay):
http://www.dynaverse.net/downloads/sfc2_op/Tools_and_Utilities/webmap_op_wips.zipAll the configuration parameters are in the mapcfg file for both maps, which I have generalised for this posting. It is geared for integration with an SMF forum. The SQL version requires the serverside shiplist to be placed in the root of the webmap folder for the webyards to work. (Geared for an SMF login). The IRC chat features will work if you use your own IRC server, gamespy has locked out other clients, but you could come up with a solution using peerchat_irc from Luigi Auriemma.
You should be able to strip the SMF integration features if desired. To adapt these to SFC3 will take a considerable amount of work, but if you are handy with a hex editor, mysql and php it should be doable. (I may yet get to it myself).
I'll keep digging around to see if I have a copy of DarkElfs D3 webmap setup.
