Additional thoughts on TRANSITIONAL

Right now IE lower-cases everything regardless of the DNS record, however presumably they could exist.   Additionally, assuming "case-preserving" really means that everyone registers lower case forms, then we have "case-insensitive" DNS, which IS fairly interesting.  It isn't hard to find links to sites using an initial upper case or camel cased forms.

English users are currently happy, DNS is "case preserving", so they can 
get or or if they want.

I tried and, and in both cases, the 
upper-case letters get changed to lowercase by DNS (*not* as a result of 
a HTTP redirect, which happens at both sites). So if English users are 
currently happy, it sure cannot be because of the casing properties of 
the current (ASCII-only) DNS, or can it?
