Would it be possible to ban the re-sale of domain registrations? This way squatting would only be done for trademark protection. I could see issues where bigger companies buy up all the related domain names to their specific industry, in the hopes of hindering future competition. Without re-sellers, that tactic would be easier, but it still might be better then the current system.
