Very interesting work, thanks for the link! We actually missed it among the references in our paper [1] and will correct this in the journal version. Regarding the differences, lsh has an interactive mode but not sshell. On the other hand, sshell compile to native (to support massively parallel calls), and IPCs between such calls (thanks to the DSO layer).
>If you count someone else's server as "serverless"
That's literally what serverless is. Serverless doesn't mean there are no servers. It is simply the ability to run your code without having to think about the server it is running on. More server agnostic than serverless.
