If you plan to use your web application without the need of a full featured webbrowser, use Warun. It loads web application like an desktop application in the line of Fluid (for MacOS) and Prism (for Windows) but in a crossplatform way.
It is still in a early version but works great in Linux and in a few time will work on MacOSX and Windows too.
Note:The project will be offline in 7 days. In order to have help on developing it and by not having feedback, I will put the project offline. Thanks for those who downloaded and enjoyed Warun!
