Would this be a good way to change your domain name without requiring all your members to log in with a password at the new domain?

I'm not sure how to answer your first question since I haven't done extensive testing. I had two domain names that pointed to different subdirectories on the same server. While structurally it appeared to be two instances of vBulletin, the subdirectories were actually mirrors.

For this mod to work, I believe the only thing you need is one of two copies of ces_cookies.php in each respective subdirectory, and you may or may not need to redefine $vboptions['bburl'] in those files. You just have to try it and see if it works for your particular setup.
