Since there does not seem to be a current solution for this, I am going to develop one with my programmer. The only question is, do we develop it just for me, or is there interest from others in making this available as a plugin? The basics: I need an easy way to maintain monthly subscribers who get invoiced and pay offline. This requires a way to post payments manually and have it interact with the member's subscription to extend it or suspend it, with emails generated to the admin upon either of those actions. If I develop this, would you be interested in it as well? What kinds of features would you want to see in it?
