Hi Raphael,
Sorry for the wai t…
Re: thirdweb - I was more thinking of sites which will autogenerate your DAO contract for you (maybe thirdweb does that too? only had a quick look), but basically something like that. I guess my main point was that I wouldn’t try writing a DAO contract myself unless I had a simple case and was feeling brave 
No reason you shouldn’t collect donations (subject to legal whatevers) - and no reason they shouldn’t be in any currency you’re prepared to accept; just make sure your contract has the ability to withdraw them again.
I think you’re quite right that the issues you mention (basically, the setup of the DAO) should be specified in the vote - I’m afraid I haven’t any views on this, but I definitely think those in favour of this plan should be chiming in here.
The governance vote might usefully include a txn id and a declaration that if successful, the funds will be managed by “this DAO right here” - that would give voters certainty over what the rules would be should the proposal pass.
