First, it's probably not hard to write a pping in other languages but c++ is my go to. (I am sort of learning javascript right now.) I think it's great if we get other versions. Secondly, for anyone who seriously wants to localize delay in their application/device/ what-have-you, I have other ways of doing that and I'm happy to discuss working with you but there will be $ involved. Finally, I've been using my infant javascript skills (see paragraph 1) to make a sort of web page display for pping and I do plan to open source it when it's not too embarassing but I'd be happy to connect with other people with a serious interest in visualizing the data in a meaningful way.
