If you do "netstat -na" on myhomemachine, you probably see that it is
listening on port 8080 only on 127.0.0.1

You could try using "-g" when you start up the tunnel from the remote
side and see if that causes myhomemachine to listen on 0.0.0.0:8080. I
know it works for "-L" tunnels, but I've never used -R tunnels.

If that doesn't work, then you will have to set up another tunnel or
squid proxy or something on myhomemachine listening on 0.0.0.0 (or
some other outside-accessible IP address) to forward to its
localhost:8080.
