Wow, now I understand what people meant when they said fan translating is full of drama.
I've only read a few things, but my iron-fisted totalitarian view is this:
If you make a translation patch and make it available anywhere online, then it's a free target for people to archive and collect it. RHDN should make its goal to seek out every translation patch, do a write up on it, host it online, and the rest be damned. None of this "it has to be submitted by the author" or "we need their permission", or "we'll host it until someone asks us not to". The site should aim to archive information in case it's lost. Other sites host this stuff and don't give a damn (several patches that RHDN doesn't carry are carried by Zophar, or pirate communities), so I find it strange that the central hub of the translation community is short-changing itself for ridiculous reasons. Do you think the national library archives remove books if the author asks? If you've made it public (as opposed to having only given to a select few friends privately), you should no longer have any rights over its distribution - with the caveat that it isn't changed from the original work. Rather than relying on authors to submit, staff should keep abreast of releases on authors private sites/forums, grab them, and put them up.
And hell, if people start selling the patches privately, have a few insiders, a few crazy moles who buy the patches, maybe crack em or rip the identification code out of them to make it anonymous, and then distribute those for free, in effect undermining the whole notion of selling patches.
Take a hardline, uncompromising stance: You don't want us to host your patches for free? Then don't make patches. Or at least don't let them leave the space on your harddrives. If it's out there, we'll get it, host it for everyone to enjoy, and never lose it. Simple as. If it exists, we'll have it, regardless of people's whining.
I realise this would never work because the community would rip itself to shreds, and there'd be splintering, and maybe some people in their paranoia might not make patches anymore, so really it's just a utopian vision which exists in my mind. In which case, if it's not here, I'll just take what I want from the various reservoirs of illicitly stockpiled internet guff.

Thank God for megaupload is what I say. Or Bhudda, if you're that way inclined.
