One thing occurred to me, and purely from a user perspective, is the password matching; it would be nice if it would only compare the two passwords when the user had finished, on blur or something; to have the text display ‘Mismatch’ from the off might confuse some people who will think they have entered a character incorrectly

I agree about the extra requests they will tend to build up if not careful with many and various plugins throwing JavaScript around.
