This is true. For what you want to do VNC or Logmein is the way to go.
There will be a one time setup challenge, but after that you should be
good to go. Also, I don't know what router your using to connect
through, but Netgear offers logs you can read to see where people have
been going, as well as site blocking via keywords. Others may offer
similar things, check yours out.
