I'm a bit concerned about the name of your project...

Here is an excerpt from Twitter's branding guidelines:

    Don't:
    * Use Twitter in the name of your website, application or product.
    * Register a domain containing twitter, misspellings, transliterations or similar variations thereof.

Hmm.. good point. Just registered TweetPlayback.com. I'll start redirecting tomorrow after DNS has propagated. Thanks for the head's up!

Those are guidelines, not rules. They can't do anything, unless they want to cut off his API access.

They can also sue. Together with disabling the app, that's plenty of 'anything' to enforce their guidelines.

Which they're very aggressive about doing...
