A note to anyone who decides to use this. I didnt analyze it completely, but this has a method for going between two disparate networks, by use of a "proxy" that appears to be hosted on the internet by OP, and any data you pass across networks is likely to pass through OPs instance. This value is hardcoded. I wont go into the obvious concerns about that.

To OP: this should be configurable, and, there is absolutely no mention of this functionality in your readme.
