JYA did this with cryptome for YEARS as a hobby.
But yeah - showing what is the money spent for would be a good idea.
But they are being openly paid by X media organisation with Y leanings. It's possible to adjust for bias etc.
For a start no one knows who funds Wikileaks.
No Governments and corporates is obviously a good policy. But that does not mean individuals with an agenda are not involved. What if it came to light that, to pick a random ott example, senior Chinese officials were personally donating?
All I'm pointing out is that it is unclear where their complete funding comes from; making it difficult to filter for any bias. If they take no personal payment that becomes a little easier, for me anyway, to sync.
I wouldn't be surprised if people don't want to pay them high salaries voluntarily.

"We don’t have to pay for our lawyer’s time. Hundred of thousands or millions dollars’ worth of lawyer time are being donated. But we still have to pay things like photocopying and court filing. And so far we have never lost a case, there were no penalties or compensations to pay." - http://stefanmey.wordpress.com/2010/01/04/leak-o-nomy-the-ec...
Authenticating the information could be done with a cryptographic signature, possibly by an unknown signer. Operate on the "last 100 0-days signed by this key when initially published were good, #101 is probably good too" basis, to build a brand.
The problem of maintaining a nice repository for the information is much much simpler, once it's already online. Google could do this for most data (just include a special string in the file), and for stuff google won't touch, there are plenty of people who would pass it around informally.
