Theoretical question for you YE's

Something that's been floating around in my head for the past few days:

Lets say in theory that it costs you the same amount of money to acquire a customer regardless of their domestic location, but you can only afford to spend the money to acquire 100 customers. Is it better to have 100 customers in the same relative location (say NYC) or to have 100 customers equally distributed throughout the country (two in each state say)?

All other things are constant too - all customers are in your target market and your product is "virtual" so delivery costs and customer service will costs aren't affected by location.

Any thoughts? I can make what I think is a persuasive argument either way (and an argument that it really doesn't matter) so I'm curious to see what you guys think.
