More than one hyphen is international shorthand for idiot webmaster; More than two hyphens is Galaxy-wide shorthand for "I'd be a spammer if only I knew how" ;)
I suspect that would equally apply to -- what's the point? But who's counting? Not me. And not Google. But it's the look of the thing; would you really spend money at [wonderful--domain.info...]
It's not only a joke to potential customers - it's an insult to the language :)
I don't see the problem? If it works for you do it!
It ain't great for type in traffic, but, that probably isn't your market anyways.
Does it look unprofessional?....well only to some Webmasters! They are most likely not your audience!
Are we spammers because we use multiple hyphens, I don't think so, we are just people who want to make a buck without paying a million dollars+ for the most desirable domain name that is currently being held hostage!
I own a lot of 5 letter no hyphenated domain names, some of which perform worse than my multi-hyphenated very long names.
Short and sweet is better IMHO, but, if you are late to the party, long and obtuse can be made to work as well :)
You know your target audience much better than I do (I don't know them at all!). If you think they'll believe that:
wonderful--domain.info/my-supa-folda/And-anotherfolda/boring-file.com
... is cool, who am I to contradict you.
BTW, allow me to refer you to Quadrille's Oft-Quoted 42nd Law

You may conceivably lose out on a few searches - eg someone looking for "ford cars" may not be served "ford--cars--and--trucks.info" You'd need to test that kind of search.
I just googled ford cars, ford-cars and ford--cars - all that changed was the adsence ads!
