That's a very sane idea. It nicely sidesteps some maintenance pitfalls, like having to explicitly list supported libraries and optional dependencies.

That's kind of a weird and AE-specific way to do that callback. A more portable API would have two methods: One to access the library's file handle, and another to be called when that handle is ready to be read.
