All the way around the doors would look SICK! A single line of blue wouldn't be bad at night. But, I think driving at night with a full glowing door could get distracting.
As for the doors, I'm going to pull off the panel and see if there is actually tape at the ends of the light pipe (which keep the light from illuminating all the way to the doors). If so, I'm taking that crap off. I want my light pipes to run smooth all the way...door to door with no stops. Great job, once again.
