I would like non-conflicting libraries as well.

I would also like to have non-conflicting packages. I don't think changing  
the names of the binaries would be that much work, but there are config  
files, scripts that refer to the binaries, etc. It's some work, but I  
think it's doable. And it would solve much of our headache. At least, I  
think it's worth considering.
