Wow, what a can of worms. It seems everyone has a differing viewpoint on what clients should be allowed to connect and what they should be allowed to do. Sounds about right for TMW

It's important to figure this out and come to some kind of agreement on a proposal that can be submitted to TMWc for official approval. This has been a grey area for far too long.. can we at least all agree to that?
Nard is right - client features can affect the gameplay balance a lot. I'd like a few more content developers to chip in their thoughts here. They are the ones charged with keeping the game in balance. GMs too as they are involved in making and enforcing the rules of fair play.
o11c you were pretty short with your post.. Can you elaborate on the reasoning for your view?
I'm still in favor of an open-access model. I know of at least 4 third-party client libraries for this game and I think that's awesome and will continue to bring good things to the game. Things like Tree, ManaMarket, Quizzy, etc add some utility and entertainment value for everyone. Frankly, this is an open-source game.. There's no way to prevent alternative clients from connecting without constantly modifying the server code or moving to a closed signed-binary model. Sometimes you just have to take the hand you're dealt and work with it as best you can. I really like Led's idea of disallowed functions.
