Um.. overkill you say? That's exactly what I did last week (used php, not ruby on rails).

And music was supposed to be entertainment..

Trademarks have a limited scope in terms of geography and product/service range that is trademarked, so:
1. If the trademark is not registered also in Canada and you are not conducting business in US related to/using the domain you can tell them to bugger off.
2. Unless you are using this domain in relation to any business which is in direct competition to the company in question you can tell them to bugger off.
3. As you have written in one of the comments below you have a legitimate reason to own the domain (the acronym), therefore you can tell them to bugger off.

Do not try to sell the domain - if you start such topic it might be considered a proof that you were squatting it with intent of resale.

Get Nokia N900 - it runs a OS based on Debian and you get root access.

Pretty simple, you'll need to get:
- a plain grey suit
- a briefcase
- a friend dressed alike

Knock on the doors and greet people with:
"Good morning sir, we're with IRS and have come here to perform a tax audit."

Warning: be prepared for the smell of urine.

True. Checking PSU, especially noname/never-heard-the-name is the third thing you should do about the hardware.
First is checking all the connections
Second is checking if getting rid of the half inch of dust +using compressed air solves the problem

The first 3 solve 19 in 20 hardware problems.

To replace hardware piece by piece you need to have replacements. When called by a relative on a Friday evening to fix the computer you don't usually cannibalize your own hardware just to have parts, do you?
