Open Sourcing APIs

Dav at AkuAku made an excellent point about how useful it would be for sites to have a secure hosted environment in which anyone can run their own scripts. This would be good for sites with large databases like Audioscrobbler or Flickr, where you want to produce output requiring complicated database queries that couldn't be run through a remote API. Maybe the PerlNomic process could provide a structure for scripts to be submitted and approved?
