This is really cool! I wonder if this will become the new "S3 API" and get everyone to copy^H^H^H^H implement it.

Also a little concerned about writing anything substantial without an onprem version!

Yes, it's my hope that Service Workers will be recognized broadly as the standard API for this.

FWIW I've seen several different folks saying they're working on implementing a Service Workers API shim on top of Node, which would be a great way to get an on-prem version, and should not be very hard to do.
