I've picked up a solid .com... it's a short two word name, easy to spell/remember/pronounce, and perfectly relevant.
I noticed the current main player in this space only registered the .com, and there is another player who registered and is forwarding to his own website the .net and .org of the main players name. I find this distasteful (and likely unlawful).
I figure if I don't get the .net and .org of my name, mr. distasteful will do the same to me.
But how important are these extra domains? Can mr. distasteful be getting any traffic other than from curious domainers via these .net and .org forwards?
How many defensive registrations are wise to do for someone on a shoestring budget?
Might trademark owners look back in five or ten years and say, ah bugger I shoulda bought all those dozens of domain extensions and variations?

Fifty or a hundred bucks a year could buy a lot of headache insurance down the road!
The above assumes that the name you have chosen is properly registered as a trademark. If you haven't looked after that yet, that would probably be a higher priority for limited funds than running around registering defensive domains from other countries.
However, don't become obsessed with defensive domain registrations. It would be easy to go overboard and register a zillion obscure variations "just in case", but there comes a point where it would be more cost-effective to leave them alone and just take legal action in the event that someone was abusing your trademark.
If you do register variants and want to know if visitors are reaching your site through those URLs, just use Google Analytics tagging in the forwarding URL when you forward your variant to your main site.
Example: http://www.example.com/?utm_source=example.net&utm_medium=domains&utm_campaign=domains
I agree Martinibuster, I'd rather not fuss with the C&D.
