I am sorry if this question is off-topic or there is a better place--feel free to move it or close with an explanation. I have no affiliation with Vistaprint.
I would like to publish a class with the name vistaprint.cls. The class is already written and provides environments for creating business cards and bumper stickers according to Vistaprint's dimensions. I believe this package would be a good place to put environments for the other media Vistaprint can use (rigid airships or coffee cups or whathaveyou).
The problem I think I will face: 'Vistaprint' is a trademark in the United States and probably elsewhere.
I am afraid of legal implications with naming this package vistaprint.cls because lawyers are big and scary and also the name could affect class/package distributors such as TeX Live. Are there any existing guidelines that would help me approach the company with a proper letter asking for the proper rights? I have perused the FAQ and had pleasant conversations with their customer service division (they told me I can't do this and suggested I write a letter).
Alternately, if your answer is of the form "this is a bad idea and you should choose a different name", please suggest an alternate name.
Edit after adding bounty:
Thanks everyone for your suggestions. At this point I will most likely use a different name. With the bounty on this question I am hoping to encounter someone who has been in this territory before.

Call up one of their competitors and see if they would like a package named after them, and then callVistaprintand they'll probably change their tune. – Peter Grill Jun 18 '12 at 20:58VPcards? Sounds to me like you underestimate the users' ability to find your package if it has a non-intuitive name. With the correct description line and read-me (both of which should explain what your class does), I think CTAN users should be able to find your package. While I would like to hope @PeterGrill is right, I am afraid to say that, usually, lawyers don't know any more about typesetting than customer support does about laws – hence they are likely to reject your request. Don't forget that lawyers around the world use Word with actual typewriter settings, like in the '40s. – ienissei Jun 24 '12 at 06:41
