It is a good news indeed.
Now decentralized blackmarket exchanges will emerge, protected by TOR and other anonymous networks.
And having legal exchanges like Mt Gox and Britcoin is also very important. I expect it to work like this:
Blackmarket goods <-> Blackmarket exchanges <-> Cash <-> Legal exchanges <-> Legal goods
Well said, sir.
I've converted foreign currencies in cash in small local shops and it's quick and easy. It's only a matter of time before they start accepting bitcoin, provided that:
1. the price stabilize
2. there are large and
legal major exchanges in every country
3. they're tech savvy
