Great work! I have been playing around it and works quite well! Out of curiosity, have you gotten this to work for a dedicated server? While i have gotten dedicated servers working in other scenarios ( Null OSS) can't seem to get one to work with Steam.
Thanks! I haven't gotten it to work. I tried for a bit. It's quite complicated to get steam online sessions to work with dedicated servers. For the project I'm working on, I fetch the server's external IP then I use VaRest plugin to write the IP to a simple database (CouchDB) with a time stamp. Then I have clients fetch the list of servers on the database and filter out ones that are more than X minutes old. I have live servers write their current times every few minutes. This way there is a basic list of live servers the clients can fetch. They connect using the open "ip" console command. It makes the server list lightning fast. CouchDB is pretty cool but difficult to use. There are other similar database systems out there. I've seen some people use MySQL. I think that's resource overkill personally. Especially if you run a resource limited VPS. JASON and a simple database work well.
I'll release this method once the project is done. I'm hoping, in the mean time, better support for Steam dedicated servers will come out. I don't want to re-invent the wheel. I've tried that in the past only to have the feature come out a bit after I finished it.
