I am technically able to reach my local computer from outside the local
network by connecting to an IP address, assuming the proper port is
forwarded to the correct subnet address.

But although I technically *can* do this, very effectively, my ISP gets
pissy if I do it very much at all. :( This whole thread is really
because I want to do one-off data transfers without running a web

availability of data that might be being downloaded. If that happens I
could be disconnected (though probably temporarily).
