At the moment, the terrain gets shadows with the bump mapping, but objects don't cast shadows, making some things look quite out of place.

Is there a plan for shadow casting features for LoS?

Nobody commented on my awesome ascii shadows.

Or the point made...

I don't think so. I've asked nekotaku on irc what was up with current development a few weeks ago.
mainly refactoring current code base. after that, putting rendering/input/network in different threads
which should help with performance for example gameplay feedback: graphical updates not waiting for input/network/whatever which should make steady framerates more probable ( just a guess )
current feature set is frozen for the moment .. I guess, I'm not a dev

personally I think shadows can wait ( I don't mis em ). I find refactoring+threading more essential which hopefully gives way to better gameplay
for example I experience walking sluggish. one moment I'm walking faster than the other. this could be because of the network stuff or graphic load suddenly rising.
if they have their own threads, it could mean that graphical/updates are independent of network/logic which should eliminate "slower walking/fps when loading terrain or waiting for ai"
and my lipsofsuna on windows experience is quite buggy.

but I didn't quite answered your question i guess. I don't now if its planned

Shadows would be nice but fixing the poor performance and some of the nastier bugs is a higher priority for me. However, most likely a whole lot won't be done in another month or so because university is keeping me really busy right now and no one else is putting a whole lot of hours into development either. So, be patient. It'll be done eventually but probably not too soon.
