Ok - I'll have to playmore with Get Books :-) -- will it know to use
several possible repositories? For example, a large deployment wants
to ship its XOs precofnigured to look at

 - the local XS (likely to be there, and to be much faster, but won't
be there for city kids that have internet access outside of school)

 - one or more national/regional servers in the sky (slower than the
XS) -- these might just not be there for rural users that have no
internet access)

 - "universal" servers -- Internet Archive, etc

Ok. Will have to read a bit on OPDS.

I imagined that that'd be the case.

We need various points of entry,

 - A directory to upload ebooks into via Moodle - for teachers to
upload new ebooks that they may have downloaded or obtained via

 - XS scans usb sticks that you plug in for certain directories -- and
if the content matches what the XS expects, then they are imported.
This works for activity bundles, etc. Adding support for an 'ebooks'
directory is easy.

 - The directory you describe -- only useful for schools that have a sysadmin...

Sure does. I am assuming that the OPDS catalogs are a bit like a yum
or apt index that clients download and query locally...
