I think that would require all our users to be sysadmins, wouldn't it?

That would be ideal. I think I also saw that discussion, or a similar one.

For now we have settled on appending a unique identifier to the dataset 
name until after the resources have been created. That way we don't get 
the URL clash if the user uploads a dataset with modified resources. A 
sysadmin can periodically purge failed datasets.
