No judge in the US would allow a grand jury to go ahead against a person that has allegedly breach an US law, that didn't occur in the US, wasn't done by a US citizen, and didn't affect any US citizens. In a way Mega Upload brought themselves within the sphere of US laws, using a .com address, paying money to US companies, hosting within the US, having assets within the US, allowing US customers, registering as a DMCA service provider, etc. These all contribute to allowing a US forum. If you set up a service like Mega Upload that doesn't have any dealings with US citizens or institutions then an US court has no jurisdiction and a grand jury motion will likely not succeed, and in most countries, other than the sycophantic ones that allow extradition on merely accusation, you can just ignore it.
