Finding a way to minimize resolution/device dependency on the content is
something that we _definitely_ need to provide a best practice for - as
it is right now, most of the sign content I have seen is severely tied
to a single screen resolution and/or software stack.

[1] CSS device adaptation is something that we should consider for this,
as most browsers have some form of functioning implementation that could
be unified at a point the standard reaches CR.

As a side question, which browser is this content designed for? I'd
like to take a look but have failed to run it on every browser I have
installed on my machine... (Opera 12, Chrome 13, Firefox 15, Safari 5)

Indeed. This could be arguably be translated as "This sign executes a
Java2D powered application packed in a JAR file via HTTP hosted on a
web server, hence it's web-based".

The transport is probably the least relevant bit here. If HTML based
signage content is hosted on a local filesystem and rsync'ed from
a server for updates, that is still web-based, even if it's not
displaying hosted content from the WWW.

Regarding the "dreaming up a fake problem" bit, the use cases noted in
the wiki list _does_ mostly cover actual use cases that are currently
covered by native sign content players in some way or the other.

The amount of functionality a average DOOH deployment provides in the
western world and Asia have a vast difference, and some of more complex 
ones are quite Asia specific - so if there are use cases that do not
make sense, please do ask the list for elaboration.
