It sounds to me like billege isn't in the same room with his lady, as he's sleeping when she's not (11am).
Unfortunately for you, I think quality cameras and full sound ring-tones are the new "features" coming to cell phones soon, because they believe your problem can already be solved by current features.
Like everyone else has said: silent by default, special ring tones for special people. As for blocking, land lines have an ability built in to do this -- and I believe cell providers are required by law to be ABLE to do this. Calling them is a bit of a hassle, but I'm sure I would do if it someone was really obnoxious enough that I'd block them on my cell phone.
In addition, I really would like a cell phone more like Trillian.. "Set All Away", email notifications... transparancies.. mmmmm cell phone mmmm
