Looking at multiple sites that exchange Bitcoin, I noticed that a number of them offer a way to deposit Bitcoin in your account by sending it to some personalized Bitcoin address.
The method in which these are generated makes me think that there must be one or more such addresses for each account.
Are there any estimates as to how many accounts on these sites need to be created to consume any appreciable portion of the total number of addresses available?

160 possible address hashes, 2
32 people on the planet. So each person could have 2
128 addresses each. That's
100,000,000,000,000,000,000,000,000,000,000,000,000 addresses each. So even if you sign up to 1000's of these sites, you'll never make a dent.
