provide a way to open the match in a (configurable) editor
Good suggestion. Any preference for the editor? (since we need a way to jump to a given line, it might take special-case code for each editor).

I'd suggest opening everything in TextEdit by default with the option to add editors for any specific extensions (like Dreamweaver does).
Supporting Aquamacs would be great. Or maybe the user can specify a command to run based on the variables [file path, line number].
