Right, however it also needs UI considerations. Like the theme sheytan
presented will entirely break with many users. This needs to be handled in the
UI/QLDM. Like having two separate greater themes, one that scales and one that
does not. If a theme creator does not provide one of the two one could just
fall back to the default.
Ideally I suppose this would actually be automatically detected. I reckon a
user list like the one in sheytan's mockup could be checked for too many
entries to fit on screen (scrollbar?) so that the greeter automatically
switches to the scalable version.
However this might have awkward side effects, like if people switch around
resolution alot, they get different experiences every time. An example here
would be if you have a laptop and a dual screen setup at home. Depending on
how this is handled it might well be that then resolution for KDM differs
greatly between dual-screen and laptop-only.
So, perhaps the automation is a bad idea. But definitely a config option should
Simplest approach is to just have a scalable versioned theme/greeter that can
be selected. Not too nice though as a theme creator who wants to provide both
experiences needs to create two themes. ;)

You'll be glad to hear that there are efforts going on to make it as simple as
running one command ;)

IMHO the best solution here would be to make it at least a KDE extragear
project, if not workspace. A lot of people watch commits and tell you when you
are doing something wrong (I prefer pizza and telly though :P).

Ubuntu Accessiblity will know, but I think that this sounds liek a sufficent
approach. Of course having a screen reader is already tricky enough ^^
