1. Allow partners to submit galleries from only one domain (or possibly a few but they have to be pre-approved first).
2. Use GeoIP to control where submitters can submit from (I know they can just use a proxy but the submitter won't know that)
3. Block proxies (as best I can).
4. Use flash instead of images for passphrase verification (OCR is getting better and better but it still doesn't work on Flash to the best of my knowledge).

The one that really interests me is #1. Are there any sites out there that are already doing that?
