I did this when I was a kid, decompiling a flash game client for an MMO (Tibia). By itself a single decompile was hard to parse, but if you do it for each release, commit the decompiled sources, and diff them you can easily see code changes. So you just run a script to poll for a new client version to drop and automatically download, decompile, commit, and tag. I'd have a diff of the client changes immediately, allowing insight into the protocol changes to update the private game server code to support it.
