And yet they didn't patent it and keep it proprietary? How unlike Sony. :-)

That's usually been my experience with UPnP. I observed this recently
when trying to play recorded TV shows on my MythTV back-end from a DLNA
client running on my Android phone. Several different DLNA clients
tried. All could browse show titles, but none could play. The video
format was MPEG2, which should be widely supported (and was claimed to
be supported by at least some of the clients).

What gives you that impression? Shouldn't DLNA hide the file system from
the client? Seems more likely to be a codec problem, or just
inconsistencies in the DLNA implementation.

Yeah, they do seem to have some interoperability problems.

But even when it works, you basically just have simple read-only access
to a collection of files. It seems to be of marginal benefit compared to
using a network file system to share files.
