Last week the nice fellow from iscandar.ch contacted us to discuss our (lack of) participation in that NWN server listing service.
I explained at that time, as I always do, that the servers themselves need no changes in order for any service to read data from the server. All NWN servers broadcast all the data needed to create a list showing the name, description, players on, and max players (and more)... we have always refused to make changes to our hosts file, we have always refused to add nwnx or any other widget to the server since we know what NWN broadcasts without such extraneous add-ons.
Pascalbrax, the fellow from iscandar.ch quizzed us on what info we could share, and we shared, even code used to create our personal server monitor software. Within a couple days, that clever fellow pascalbrax had included the features we coded into the iscandar.ch service, such that now, the iscandar.ch site still takes feeds from skywingL's (host file modification required) system, but if a server does not give up the data on that basis, iscandar.ch now runs code based on our shared code and reveals all the needed info without any requirement that the server be modified in any way.
KUDOS to pascalbrax for offering this EXCELLENT service, the BEST NWN listing service on the Internet.
