with the emergence of distributed dns's such as namecoin, could the fundamental logic of domains be redefined alltogether?

could a url be made to look like this?:

protocol://space.subspace1.subspace2.subspace3/folder/file?=POST_DATA

with 'space' being the domain name and the idea of TLD's and country name suffixes dropped entirely?


I'm writing this because I had a science ficticious hallucination last night and a white-bearded guy with a pointed hat and an e-cigar told me the domain name system was gonna be renamed to 'space name system' (SNS) and that those www.'s and dot-something's were gonna be a thing of the past.

I also saw something about desktops disappearing and 3d nodebrowsers...uh never mind
