Is WP up to the task?

I just found out that the manufacturing company I work for is considering expanding it’s web presence and it’s customer relations by offering our customers a way to check on their projects via the internet.

Since I went and opened my mouth I get to do the research. What I am looking for is a way for our customers to log in and be restricted to just their project information and nothing else. The information that will need to be available are current/realtime photos and current project manager notes.

I’m not needing a project management solution. Just something that the customer can use to see where things are today without having to fly in from where ever they may be. Since our customers are located around the world, not only are the trips time consuming they are expensive.

So, the question is; can WP provide customer log in from a static front page and direct the customer to their project information and their information only? Also, will they be able to have access to archived information on their project and leave comments?
