KF SDK concerns

Hi guys, I have just had an urge to use my software engineering experience to produce something more fun then stuff I do at work. Now, I did a little research into modding for KF and it appears to be much more simple then I anticipated, but a KF SDK is pretty much necessary. I have read here http://ift.tt/1vJZxQZ that it messes with your firewall, and adds tasks to your scheduler, to initiate connections.



Can somebody shed some more light on this? What is the purpose of such connections? What else does it do without telling the user?



Thanks,
