>>3147>run it over 443
This is a really key thing because that's the port that HTTPS runs over. The sysadmins can't actually tell if you're using a VPN, they just know most VPNs run over some other port and that HTTPS runs over port 443. If your traffic looks like HTTPS to them, they won't do anything.
Also, I think you could run a VM and pass your wifi or ethernet into the VM, and then get the internet through it. However, I have no clue how you would do this. You should be able to do something like this with a cheap physical machine as well, and it's probably easier.
