He, She, and It

While making up the wiki page for He, She and It this week, I was wondering if the House was a character in the book. Unlike the other house computers, Malkah's house was programmed to be more personal. The house even offered advice to Shira when she was younger. But does that make the house a character or a very sophisticated piece of technology?

So Yod's a cyborg and we hear about apprehension of the human side, but the machine side doesn't put up much resistance. Gimel and the cleaning robots didn't seem to care (can they even care?) about Yod. The only resistance to Yod from techology comes from Malkah's House. I'm not sure what to call the House exactly, she or it?, but for the purpose of this post I'll refer to the House as she. She refuses to let Yod in or even call him Yod. To her, he is a machine and no amount of artificial intelligence can change that. Is this just how she's programmed? What separates her from Yod in terms of programming? Is it her inability to disobey orders?

I also found out that He, She And It has an alternate title Body of Glass for the UK version. Why would Piercy have two different titles? I can see why she would pick He, She And It but why Body of Glass?
