If you have time to write, I want you to proceed with development.
I develop it now full time, otherwise I wouldn't announce it here. Of course will update in some intervals and hope to have prototype working in pretty reasonable time.
I can do Vietnamese translation for bounty if this project has a translation campaign 
We are still on very early stage, so now bounties and alike aren't our main concern. But we'll keep notice about you being first re: translations.
