When I freelance, it's usually at places that already have their own bug tracking, and I use theirs. Would this be for people working for clients who aren't software developers?

It seems like you would be competing with things like Google Docs.
Even in my scenario I often have higher-level "stakeholders" reporting bugs to me via email, skipping over their own bug tracking systems.
One challenge would be making it more appealing to those bug reporters than using email. Maybe you can have it receive email and parse it into a bug? For people who won't sign into a separate web app.
