I think the word serverless is being used from the perspective of whether you have to maintain it yourself. Its just outsourcing, but that is a bad word so let's make a better trendy word.

Things like Bitcoin and Bittorrent would better fit the word serverless. However, you need servers of a sort for Bitcoin to work (e.g. you need nodes and miners) and you need an initial seeder for each torrent to get going.

Since serverless seems to be mostly about a class of applications, I think only those that function either without network access or without contacting any specific organizations computers (i.e. servers) would qualify. This would make my browser fundamentally serverless, since I can browse files locally. Suddenly my browser seems like a glorified file viewer and One Note is rsync with an editor attached.
