I am quite aware of the potential risk of being sued, but still I don't 
know what to do about it. Isn't this a general problem when creating (free) 
software? The patent you mentioned could easily be applied to Sage as well 
– so how do you deal with that there?

Should I contact Wolfram and explicitly ask whether they're "okay" with 
Mathics? Could I trust a "yes" and should I just accept a "no"? Given that 
I'm not a legal expert and don't have the money to hire one, should I 
rather take down Mathics completely to avoid any risks?
