I know that it would be completely impossible for me without some third party company providing an intermediate to make it work. It's not merely against their terms of service (home users shall not run servers) but you simply can't reach 10.x.x.x addresses from outside.

Simple test: Open a command prompt and type: "tracert www.google.com" (without the quotes). Look to the right. You may get 4 numbers, you may get a name followed by 4 numbers in brackets. Chances are the first line will be 192.168.x.x. If the second is 10.x.x.x your system is unreachable from outside.
