Unfortunately, now we've circled back to where we started.  Remember that 
the NC in NCAP stands for Name Collision, and the whole point of the 
project is to figure out how risky it is to add familiar looking new 

In the last round of TLD expansion they added over 1000 names but 
indefinitely deferred requests for .CORP .HOME and .MAIL which had well 
known existing uses.  So now I'm scratching my head, what are they hoping 
to learn from this exercise that wouldn't be totally dominated by the 
choice of name?  I'm tempted to suggest adding .BELKIN and see how many 
old routers fail.
