As the title says, go open source with AO. Or at the very least, do a semi open source to the extent that AO players get a development platform to work on the important parts of AO, though not necessarily all of it.
Provide players with a way to gain some sort of access to the AO code and let them try out fixing and making improvements on things, then take the best of those and implement them on live servers.
It's the most revolutionary step you could take as a company, it would make AO a hell of a lot better because things would get fixed faster and you would draw on a larger creative base of talent for new things, and in all honesty, it's where gaming is going to head eventually anyways. You can be the first to recognize it, or you can wait for someone else to do it first.
