No seriously! Least square conformal mapping cannot work unless one chops up the UV into nice small pieces. The original authors never claimed it could, either, which is why they presented a method to find such nice pieces in the very same paper.

If you want to map more complicated charts in one go, you have to use iterative methods like the one in UVLayout. Seriously, if you've every tried UVLayout, everything else on the market - including Blender and Houdini, for what it's worth - looks just pathetic.

Side note: Roadkill doesn't work on my machine, anyway. If I got a penny for every free, badly written WIndows-only program, I'd be rich.

As for the point you make about projection mode: completely agreed. If done right, it's the best way to avoid or componsate for distortion. With a software that provides a good interface for aligning the source images with the model, I can't imagine any easier way to texture. I was just talking about my personal experience with a very limited selection of software. DeepPaint is a bit outside the range of what I'm willing to pay for 3d software, so I can't say anything about it.
