GWT on YouTube
Combining YouTube api and GWT is by far one of the best experience I ever had and at the same time one of the most difficult to work with. The opensource community has been working hard to create a patch for GWT developers in order to make it easier for us to work with Youtube stuff. Thanks to bst-player things have been very good to my project. Here's my sample project: I am very much satisfied with the results right now but still I would wait for the real YouTube api to be compatible with GWT.
