Wing IDE Professional is awesome. sshfs is awesome. Massively large codes bases are, well, sometimes you're stuck with them. But note, Wing IDE, sshfs, and massively large code bases don't mix; it's slooooowwwww . Use NFS instead. By the way, the ability to run Wing IDE on my Linux laptop in order to debug a process running on a remote FreeBSD server (using stackless Python no less!) is fickin' awesome!
Ad maiorem Dei gloriam inque hominum salutem.
