Ask HN: Would a mockup presentation tool like this be useful to you?

This is probably more relevant to designers and people who frequently present design mockups to other people like clients and colleagues.

I'm a designer and part of my job is to present design mockups (web usually) to clients and colleagues and to make sure the mockups look accurate (like they were in the browser) I would put them in HTML pages so the images and background and margins etc are nicely done. I then upload the assets to a subdomain of my blog or S3. I would then explain my design in an email. It's a major hassle and not the best way to communicate design choices.

I created a tool called "Mocku.ps" that simplifies this process into a few clicks, with annotations like the what you get with Bounceapp.com. And then you just share that nice shortened URL.

You can use it at http://mocku.ps/.

Do you have the same problems as me? Is this something you would use often? Is the interaction simple enough? Would be great if you can try it out and give me some critique.
