How about officially supporting Teleport?
There's a very useful app called Teleport which allows you to share a keyboard and mouse between multiple computers. The developer, Julien Robert, works for Apple in Paris, France, but it's a poorly maintained, and it breaks every time a new major release comes out. We have to wait months for him to change a couple lines of code. Currently, it's keeping me from buying a retina mac, because my stinking "Free" mouse sharing program won't work if I do.
Dear Apple, please let the guy support the product on your dime; or better yet, add it to the OS. It's a very useful product. People who use it own Multiple iMacs. We're good customers. Make our lives less stressful, please.
