I just registered hnypot [dot] info for a few bucks and will see if I can get wildcard DNS running with some tracking. Haha, I don't want to type the name as a link until I get the tracking going...
If anybody wants to collaborate or you just want an NS delegation off that name to try to roll your own, just let me know!
It is a short name, so it's likely that it'll be found. But the real honeypot would be the large hashed subdomains that you would use as bait.
I don't think the main site or its www subdomain would need to be secret. Of course, if it uncovers some huge invasion of privacy, we might have to set up an army of different domains running similar software on separate IPs to keep it effective.
