NY-based CoTweet provides an application that allows multiple people to access one Twitter account. The idea is that this idea works best for your “brand.” Company Twitter accounts built not just for individual users. They describe the service as “team workflow for Twitter”.

 Don’t just give a password out to anyone who needs to post to an account. The application is actually pretty slick – it tracks which person made the reply, offers the ability to forward tweets to certain people on the team to respond to, etc.

The service is currently in private beta but they expect to open next week.
