Is there a middle ground where you build a web app, and then offer a desktop app for people willing to install it? For example, I want to write some lesson planning software for teachers. It would fit the web app model well for many reasons, but there are compelling reasons to make it a desktop app as well. I plan to build the web app first, and with traction offer a native app. This seems to parallel the current trend of building a web app and a separate dedicated mobile app. It's extra work, but done right it makes a powerful suite of ways to distribute your product.
