The module already supports all the functionality required in order to build an AnyEvent layer on top of it (including async disconnection support). So, it shouldn't be too difficult to do so
Actually it has been in my mind for a long time as I am also an AnyEvent fan, but unfortunately my spare time is scarce.
In any case, you can just use it on AnyEvent without wrapping as follows:
1. Call the constructor with async => 1
2. Using a timer call $ssh->call_for_master repeatly every 0.1s until it succeeds (or you get an error back).
3. Use 'make_remote_command' to get a command you can pass back to AnyEvent::Util::run_cmd
For disconnection, there is an undocumented 'disconnect' method accepting an async option.
1. Call $ssh->disconnect(1)
2. Repeatedly call wait_for_master until you get a defined but false value.
And you are done.
BTW, you should be using the latest development release as I have reworked the async disconnect support there and solved several bugs.
