Assuming Nelson is the 'source':
It's going to be difficult to prove either way. Unless there is some hard evidence that has been uncovered (such as trigger phrases, like the "Alonso has pitted" which haven't been used at other races, or some horribly irregular telemetry), then you're relying on word from at least 1 disgruntled employee (there could be others lower down in the chain, but you'd expect the only guys in the know to be only the ones who need to know) or someone who's got a grudge against his team. How far would you trust the word of someone who's been fired and used every opportunity prior to this to have a shot at his team or former boss?
I hope the hearing is treated with total public transparency, as I'm rather intrigued by this.
Whether or not Renault pull out if found guilty... well... should they be in the sport if they're going to pull stunts like this?
On the flip-side, as Dave pointed out earlier, and as Bernie sort of pointed out, is it really such a big deal? There's no specific regulation about it - it's just covered by that rather large umbrella of 'bringing the sport into disrepute' that crops up whenever something mad comes along that no-one has thought to cover in the written rules.
//edit: OK, so there is a regulation (though it's quite flimsy itself). I really should have read first.
151c: "Any fraudulent conduct or any act prejudicial to the interests of any competition or to the interests of motor sport generally."
