Good point on the small target audience.. It really is a shame because this is a great looking project.
I think I should write a web app that handles the SHH connection on the backend and renders the SHH app into HTML so that they can be enjoyed by the masses.
If you do this, please mention that using a proper terminal + ssh will work better(This is based on my understanding of technologies used, but I could be wrong), and you may be responsible for a lot of people taking their first steps into knowing computers a lot better!
