not sure if you meant this with

This will enable websbot and improve the situation on mobile, etc too.

but finding a quasi-final point for this interface (trying to ditch the word standardt) would also make it more interesting to work on alternate sbot implementations that could feed the same UI.

taking the flume(view)-rewrite asside (since flume might remove the need for them), would the current ssb-plugins (like -query and -links2) be fine with this api? meaning could they work on top of it or do some need closer/direct access to the indexdb? might be a good hook to see how good the design is...
