Neat stuff! You can finger billstewart@wasabi.io.com, even though I don't exactly have an account there... Is the source code available for your finger daemon? It doesn't seem to have any regular-expression matching; it mostly matches exact character strings, presumably case-insensitive. I couldn't figure out how to get it to match spaces, though: requesting 'bill stewart' got all the bills and all the stewarts, rather than getting the lines with bill stewart in them. Thanks!
