Yep.

Yes, and no.  Not in the .newsrc.eld format AFAIK.  And not the entire
file, just a subset of it.

With couchdb that information is stored as JSON documents.  I have no
idea what the current file based sync looks like.

The gnus-sync-read function reads the latest info from the sync server
and merges it with the current .newsrc.eld content.

The gnus-sync-save function saves the latest changes as updates to the
JSON document for the group in couchdb.  I have no idea what it does on
the file version.

Those are the only two functions I use in practice.

When I start gnus, I do: `M-x gnus RET M-x gnus-sync-read RET g' and
after the g I will see the updated read counts for the groups.

When one of my gnusen have added a new nntp group and do gnus-sync-read
on another gnus, I am asked if I wish to add that group.  Ditto with
topics. 

When I want to save, I do: `M-x gnus-sync-save RET s'

It's a little bit fragile:
 - If I forget to gnus-sync-save I may lose all read marks I have added
   in this session, because the gnus-sync-read of a new session will
   overwrite my .newsrc.eld status with the older status on the server.
 - If I forget to do gnus-sync-read at the start of the session and then
   try to do gnus-sync-save I am told that I can't gnus-sync-save until
   I've done gnus-sync-read (which will overwrite my current read marks
   with the older saved one)
