No problem, right now I just use an nfs export. But - like miniDLNA - this is 
not aware of all the data that's stored in the digikam DB:(

That's where digikam has to be run on my desktop pc again:( I wonder what the 
best solution would be to use the data in the digikam DB without a full 
digikam installation (like on a tablet). First step could be read-only 
("filter by tag to show only certain images to friends on the tablet"), second 
step "use tablet even to assign tags while browsing images on the couch")... 
Android app? Web interface run on the NAS? Need to write everything into the 
files and can't use any of the advantages of the (already existing) database 
(like performance when filtering...)

The uniqueHash that is stored in the "Images" table. I think this is used by 
digikam to identify images that, for example, have moved to another path since 
the last start of digikam (so that metadata won't be lost)?
