I'd like to add a configuration option for a "Crypto Party" mode (or however you wish to name it).
If that option is set, all gossip and other connections to keyservers are disabled completely. Moreover, the web interface provides a "Delete All Keys" button at an appropriate place.
Background: At crypto parties, among others, beginners are taught how to upload their keys if they chose to become part of the WoT. Usually these are test keys, perhaps including too much personal information by accident, having wrong key sizes, and/or are deleted afterwards and are hence just worthless noise to the WoT as a whole.
So I'm maintaining an SKS instance to be used at Crypto Parties that behaves like a normal keyserver for uploading and downloading, but with disabled gossip, where I manually delete the whole BDB directory from time to time.
I'd like to automate this. Of course I could put a separate web interface around it, and script the database deletion. However, I believe it makes more sense to integrate this feature directly into SKS, so that others can use it with less hassle than what I'm currently doing.
