Does namereg allow uppercase I and lowercase?
If that's the case, then Namereg for 'VitaIik' and 'VitaIik' just g0t pwn3d, one of those is uppercase and other lowercase, anyone using standard fonts on mac osx is going to lose a lot of money from phissing addresses.
If the embedded contract accept Uppercase and Lowercase. I wouldn't like to see scams.
By the way, Ethereum address are always lowercase https://etherchain.org/statistics/olympic
