The trick is the source of your TLEs.  If you get your TLEs from a foreign 
source, then you can do whatever your agreement with the foreign source 
allows.  Does anyone know of a good non-restricted, non-US source of TLEs?

However, if your source of TLEs is derived from any US source, then your 
source will stop distributing them to you by the end of March unless they 
want to go to jail.  By the end of March, the only way to get TLEs from any 
US source (government, NASA, etc) is through the registered website.  If you 
get your TLEs from this website, it is illegal for you to distribute them. 
Period.
