Cookies isnt a good method to track signups anyway, sponsors need to change the way they track signups.
And the traffic trading can be solved too.
Send traffic to a URL like this:
www.domain.com/yoursite.com
or something, we just need new and better scripts.
The samething with sponsors, they can use them same method instead of using "?affiliate=someone"
Most of that stuff can be solved, BUT "noone cant visit sites no approw by microsof", that is just retarded.
"Longhorn will secure that noone can use unlegal software".
This can actually be a good thing.
I think opensource will grow alot cause of this.
