I don't think that a new editing suite would have a chance, being used to something is as much of an incentive to use it as something being better. Not many people would switch from Vegas/AE regardless of how good it is, unless it's completely free. I think a lightweight lawena-type tool would be the best, something that could emulate the source recorder, only with a responsive developer base.
Anything but local recordings are a bit silly, you might as well just save it locally and then upload to whatever you want.
