Technical/Legal Question

Blogger annoys me, and for various reasons I am seriously considering the jump to MT and my own domain.

My major hangup is that I don't want my address and phone number available to anyone who knows what a WhoIs search is.

So, my question is, is it possible/legal to register for a domain using false information, or are there companies that will register for me for a nominal fee, or is there some other way to prevent technically-astute Freepers from finding me and killing my dog that I haven't thought about yet?
