There's no project currently :-) Starting from Matts code is probably the way to go. It's written in PHP. Alternatively, you could write a Java app for it, as there are drop-in DNS serving libraries you could link with BitCoinJ+sqlite. It probably wouldn't be that hard. You'd want to sort nodes by version, how long they've been observed to exist, the last polling time, etc. On Wed, Aug 3, 2011 at 4:00 PM, Rick Wesson wrote: > Mike, > > I think I can contribute to your DNS seeding project.
