This case keeps getting more interesting. Julian Assange, while out on bail in London awaiting his surrender to Sweden, has now sought asylum in the Embassy of Ecuador. The Ecuadorian government, whose President has apparently made sympathetic noises regarding Assange's plight, are considering the request. Coverage here. As correctly noted in the BBC's Q&A on this development, the UK police cannot enter the embassy and arrest Assange because of state immunity.
One of Assange's former lawyers has speculated that he will try to use any protection Ecuador gives him as an opportunity to negotiate with the Swedish authorities -- specifically, to have them agree not to re-extradite him to the US to face any charges there once the Swedish matter is complete. Re-extradition will be within the discretion of the Swedish government.
Assange has been criticized as constantly seeking the spotlight and making legal maneuvers to try to keep the spotlight on his Wikileaks mission, so for the cynical this could be perceived as another plank in that platform. On the other hand, Assange quite reasonably believes that he may be the subject of a secret indictment in the US (which is available in national security matters), and the US government has maintained a rather stern posture towards him.
Before one yells "conspiracy theory," it is worthwhile to note this: it is well documented that various companies which had been providing Wikileaks with commercially-based internet services unilaterally withdrew these services when pressure was applied to them by American politicians. In the story above, the US's Ambassador to the UN Human Rights Council was quoted as saying "getting too enamoured with the idea that Julian Assange is a whistleblower missed the reality that confidentiality on the part of governments is not all bad."
Perhaps an appliation of the adage, "just because you're paranoid doesn't mean they're not out to get you."
