Wow, we are going to get tons of Alias squating!
Since this is the wild west with no centralization people can start registering trademarks with impunity right? Things like eBay, eBay.com, Overstock, Overstock.com, Amazon, Amazon.com etc.
But, isn't an alias tied to an account or url, or can you edit those things after you create the alias?
Lots of aliases are already registered, more than one hundred thousand atm.
I think no dots allowed, ebay.com not possible
The owner of an alias can change the url (read here

The real novelty is the possibility to transfer/sell a registered alias.
