Sweet—can't wait for this!

From Signal vs. Noise:

Outpost (coming in August 2008 from Morfunk) promises to let you manage your Basecamp projects on your iPhone: "Take notes away from the office. Delegate tasks from the train. Check on deadlines. Upload photos to projects. Anywhere."

Sign up to get notified when it launches.

I'm an avid user of Basecamp, but had never heard of ProofHQ until I read this 37signals blog post: ProofHQ and Basecamp: Offer your project team richer review and approval tools. It seems ProofHQ is a "web-based design collaboration, proofing and approval tool for brands, agencies, designers, print and production" which can be integrated with Basecamp. Cool!

I just signed up for a free account with ProofHQ and am going to attempt an integration.
