This looks like something that would be useful to me. As I've been wanting to have a decent C++ IDE that I can run on my server and access on any machine.
I've tried to use Vim+ctags over ssh for this purpose but am not really satisfied with the results.
I do this all the time. You want the Vim plugin YouCompleteMe[1]. It integrates with clang and gives you real-time C++ code completion and linting, plus a semantic jump-to-definition that outdoes ctags for most symbols (though it doesn't go outside the translation unit so ctags is still useful for finding implementations).
I have been using it for 1.5 months with zero issues. I recommend it if you're using neocomplete, the configuration is nearly exactly the same so switching to it and then back again is not a hassle.
Yes I've tried YCM some time ago and decided it didn't work acceptable for me. It didn't find all the candidates for autocompletion and wouldn't work if there were any compile time errors.
Anyways, autocompletion and jump-to-definition weren't all I was missing. Smart syntax highlighting that could deemphasize macro blocks (eg. #ifdef) that would evaluate to false for the project is some thing could not find a plugin for.
