We also sell vanity tiny URL shrinkers over at http://tinyarro.ws http://tinyarro.ws -- revenue is light but there are a good number of people who want control over their own domain shrinker. The hosting costs for high levels of redirection are obviously quite light overall. TinyArrows was more of a silly/fun project to see what we could do with unicode-based URLs. But we figured we might as well let people run their own domains off of it since we already supported so many domains. We've also discussed with some marketing firms the idea of getting into meat-space advertisement. Basically where having a tiny URL people can visit with a smartphone (to see videos, etc) could over time become a great backup for stores with reduced retail salepeople or for home virtual tours, etc. QR codes aren't as universal as URLs are, so there's some mild opportunity here.
