... on a related note, something we know we'll need to implement is res=
ources=20
being "clients" to other resources. The obvious use case is moving emai=
ls=20
between folders that belong to different accounts ... but archiving is=20=

another.

What we'll end up needing to do is to have a way to tell resource A to =
move=20
entities { ... } to resource B. Then resource A will connect to resourc=
e B the=20
same way any GUI app does and send it NewEntity commands.

The benefits are that we can ensure moves are atomic, there is a minimu=
m of=20
inter-process communication, and then resource B can present a view to =
clients=20
that makes sense .. whatever the format.

So even a tar.gz based system could send entities as they are added thr=
ough a=20
pipeline which includes full text indexing[1] so that one could at leas=
t find=20
the archive a mail is in.

[1] best would be to move the old FTI results over to the new resource.=
 There=20
is a fair amount of pipeline filter design though left to do ...
