People are always hesitant and if they have their own hosting solution then of course they would prefer to not spend the extra couple of dollars... which thats exactly what it amounts too... a few dollars. I have my own hosting solution and I use WebRcon which is cool and a half way decent tool, gives me little to almost no troubles at all, but it just lacks a lot of other functionality that I'm looking for.
B3 is over complicated to even setup so if I was to choose that (which I was looking into prior to sCon's release) I would have gone with the premium hosting they have listed on their site...
BTM has no option at all for real hosting (or at least without your own VPN) or running it from your own computer which has to stay on 24/7 (no thanks), so I chose to have that hosted as well.
sCon is seriously gearing up to be thee best of all the worlds combined... take all the features of WebRcon, then mix in all the features of BTM and then toss in a majority of the features of B3, then sprinkle in some more features and what does that make? sCon... the "Smörgåsbord" of Rcon Tools.
And personally I think it makes more sense to keep the tool private and hosted the way it's being done now. All that releasing it would do, is create more headaches in the long run for the developers as they have already vested a lot of time and effort in making it stable within the environment they currently use. Toss it out there for everyone to use and next thing ya know the devs are getting bombarded from all different directions for support across a multitude of systems and setups and its a recipe for disaster.
Look at the current affairs of PC titles and we all know why us PC'ers get the short end of the Port Stick... because its easier for developers to mass produce games on consoles since they all use the "same" hardware and its much more difficult to deal with the vast amount of PC hardware, software and setups.
Keeping sCon private and self hosted means "one" thing... it will always be more stable... it will make life easier on the developers... which means the developers will have more time on their hands to continue improving on its functionality... which ends up being a better product for us Admins in the long run.
First off, kudos for writing such a long well thought out post. Sorry my reply will be much shorter.
It boils down to this: If I must reply on someone else to keep it hosted, then I won't use it. Its why I won't rent a BO server, its why many people want the server files. We don't trust anyone but ourselves.
I don't want to deal with GS support, just like I don't want to deal with sCons support. It is not about the money, but rather who has the key in the end. And if it not me, then I won't use it.
And don't start with the "well you gotta rent a server, even to host your own stuff", as renting a server for over $150 a month and renting some space for 3 a month are not the same. I only pay the people I trust, and that applies to all aspects of life.
