I have had great success publishing my prototypes directly to my Public Dropbox folder. I have been using Axure for web, iPhone, iPad, and TV interfaces (10 ft UI). Once your prototype is published to your Dropbox public folder, you can get the public URL for the "home.html" file, and send that around to coworkers and stakeholders, and you can even do usability testing on it with services like Usertesting.com.
If you publish for mobile, you can set the viewport zoom meta tag, as well as paste in a meta tag that strips the mobile Safari browser chrome once the page is added to the home screen of device. A nice html5 pseudo-native prototype
