I noticed this with calls/SMS between myself and a local bike commuting pseudo-stranger whom I gave my GVoice info to, instead of my real phone number. He gave me his real number, but when I SMS'd him, it appeared to his phone via Google voice's SMS system. While it's cute and clever, it's not right. He was a bit confused, because he only gives his Google voice info to certain people. Knowing my background as a geek, he figured that I'd somehow compromised something just to show off, and was none too amused about it.
