US trademark law is limited to (a) commercial context and (b) possibility of confusion. If you aren't selling anything, or even if you are commercial but are in a different line of business, you should never be troubled by any trademark claims. This is how the old Beatles record label and the computer company can coexist with the 'Apple' name.
Probably many of us here are in similar situations - I have a domain name for example in .net and .org, but someone else has the .com. I don't want to take the .com from whoever it is (not without their consent, that is), and I shouldn't to have to pay for lawyers to fight them off if they make the name better known for their unrelated site.
