Yes, I was aware since Fabien talked about it offline at Ada Europe in June.
AWA is using AWS but can also be based on EWS. I also have a prototype of server based on Simple Components from Dimitry but it has some issues.
AWS is still a good choice for me as long as it is open source.
The question will be whether Ada Core allows the open source community to take over the project and continue if some developers are interested. Personally, I already have some specific branches that solves build issues on NetBSD or FreeBSD (by getting rid of GNATColl dependency which brings lots of complexity and build issues).
