I wanted to offer the software to other servers, but there are some problems.
Firstly, the STCC is a lot bigger than most people realise, it's extremely comprehensive. It features a full back end web interface, and it runs on the server as an application - not as a service. It's an extremely verbose and comprehensive software package and it is still being developed, and with the new version of insim - currently it is being rewritten from the ground up.
The problem is that much of it is very specific to the STCC. The other problem is that there is a general consensus that the STCC system would not be welcomed if it became the only way to get an online race.
To combat these last two points i've invested and continue to invest in expanding my own services, whilst trying to finish off the first season of the STCC broadcast league, and updating to the new version of insim.
It's far from complete, for instance I am testing out new private messaging functionality and public chat channels (sending PM's to groups). I plan to tie this into a multi-format (Mac/PC/Linux) instant messenger application (dont panic, it'll tell you when the person you are messaging is racing or if they are idle/spectating).
There's single seaters and GTR's which are not yet even represented.
There are features which are not finished and features i've still not got around to writing.
In short, it's just not ready to be given away, and I honestly dont know if it ever will be.
Some of the features are available in existing applications though, i've not used it but VCom does track changes and restarts I believe? Also LFS Lapper does an aweful lot - the only problem there is many server admins 'turn on the spam' instead of using it more discreetly.
With the new developments in INSIM it becomes ever more likely that other INSIM programs can deal with just small aspects and lots of these programs - when they appear - can be used together.
As for me 'keeping it to myself'. Well, I think there are many server hosts who'd be willing to bring things to the table rather than say "can I have your system or i'll call you names" - and they would be far more deserving, I think... We already provide services to some other leagues, we in the SRA (and it is more than just me) just havn't found the need to shout about it.
Anyway at this moment in time, INSIM is about to launch in a brand new form on Patch X and NOBODY, including the STCC, yet has any software at all.
