Unlike Tor addresses, you can actually do bespoke generation for other people without being able to get the private key. There are a few vanity pools that facilitate this, but unfortunately they don't reward partial work and aren't very popular.
I actually came up with a way to make a vanity address pool that would reward partial work, and got fairly fare along implementing it before I realized that the market for it is probably too small to be worth the trouble.
