Basically, I only want the people to whom I give the link to to have the plugin (of course, anyone who happens to stumble across my repo could get it too, but I don't want to "publicize" it per-se).
However, I still want to be able to take advantage of the auto-update feature (that I'm assuming) that skpm gives you (so when I update the plugin, people will do have it installed will be notified and be able to update it).
Thanks!
