Love this idea. I use Talkerapp a lot with a lot of different teams - web based, clean, does things like shows images inline if you post an image URL, persistent logs so people can log in and read up, etc. It's free. I'll check Tinychat too, I'm really interested in everything that can enhance remote team collaboration. I do a fair bit of outsourcing, so this tickles my interest for sure I'll work a little bit on the dropbox idea. It's not rocket science at all, it's just setting up the proper privacy settings on the shared folder, and making sure people actually use it. Then I can build a simple image showing web service with minimal UI - just organizing the screenshots for a web view based on folders, on a pw-secured server.
