I use Levenshtein matching for a small business. We take in orders, and some of them end up being ordered from a partner that ships them out. They often change the shipping address in small ways, and don't provide a nice api for us to match orders to tracking numbers. Instead, we just get an email from Fedex or UPS.
So, we trawl IMAP to extract the addresses and find close matches for open orders with Levenshtein. Not perfect, especially when one customer places more than one order, but saves us a lot of time.
