Know the biggest issue I've had with Node (well not me, but my colleagues)? That modules have a habit of using symlinks, which break horridly across Vagrant/VirtualBox shared folders. We ended up fixing it somewhat by using the --no-bin-links option on `npm install` and swapping over to SSHFS, but I really wish module writers would pay more attention to Windows... one of Node's strengths is that it works pretty darned well on Windows (just like how XAMPP made PHP deal with windows well enough for a large developer base to grow)
There's no reason why node/npm can't implement a thin filesystem mapping layer on Windows and map long, logical module paths to shorter filesystem paths. That sort of address translation would fix both the symlink and the path length issues.
