I can see your point, I've been running a twitter account so you know what versions are on the server.
I only post when the AAOTTS game servers have the map uploaded and ini files updated. This lets you know to go and download the updated or new map and it will match the version on the AAOTTS game servers.
151Alpha was doing the same, however no recent posts.
Our twitter url for the game servers is
twitter.com/aaotts
We have the last few posts on this web site, replicated from twitter on the menu Downloads > Map Change Logs
The suggestion about the server list showing the version would rely on the game admins of those servers to update the info, I don't know of any automated way to get that info.
Hope the twitter account helps for now. The difference is a map may get uploaded to the web site but not onto the game server for a few days, this is when I post on twitter.
Enjoy the games
