I used to host at least some of the Simutrans stuff - I remember with a little pride at the monthly bandwidth.
I've had some rough times which caused me to temporarily back away from hosting (which I have always highly regretted); I don't remember if that was a contributing factor, but I believe devs found it better/easier to use tools designed for the purpose.
That being said, if at any time anyone wants to move stuff or just copies of stuff somewhere on the server, of course I'd be overjoyed.
There is a possible tiny wrinkle in that I, of course, do webhosting on my server and it's a CloudLinux/cPanel environment, which is geared toward keeping shared hosting separate from each other, so there's some stuff the server won't support, which may prevent it being a good option.
But if whatever tools needed are able to be run, I am of course very happy to host anything desired.
