Editor

It'd be valuable to have an editor mode, at least for emacs (which is widely used), and in the future maybe Eclipse.

Arne Babenhauserheide has a mode for wisp https://bitbucket.org/ArneBab/wisp/src/tip/wisp-mode.el available as an emacs Marmalade package: http://marmalade-repo.org/packages/wisp-mode/0.1

Supporting/working with ParEdit is considered especially desirable by many.
