Finding Mirrors for the evolt Browser Archive?

MartinB asks: "I help out running evolt.org, and one of the things we provide is a comprehensive browser archive, with over 100 different browsers, some in multiple platforms and versions, going right back to Mosaic 0.4. This is both a piece of web history, and a resource that lets developers test their sites on browsers which vendors don't offer for download any more. We have an expensive problem - the browser archive chews through 140GB of bandwidth a month and growing, even though we've throttled the FTP server and restricted the maxclients. How do we find people who provide mirrors like these and get browsers.evolt.org spread across lots of hosts?"
