well, thinking about the shutdown of google code and the need of a new hosting for terrasync today, i've had an idea: what if there is a repository for the airports apart from a scenery one?
Let me explain: even in the new WS2.0, there are tons of airports using the old .810 layout,and even with only the runway. And i know that even in the next scenery build it will remain some of these. So, my suggestion is, for creating(i could not think about the "where" yet) a repository containing all the airports of FG, apart of the main terrasync server. these airports could be downloaded individually(just like the livery database), and used as custom scenery, so would be much easier to have an updated airport layout, without having to wait until the next scenery build. the airport package downloded could have the ICAO.stg file for scenery use, aswel as the .wed file for the case the user wants to generate the airport himself or update it by his own. Also, the data from the x-plane gateway could also help in this.
I hope you enjoy this idea...
