I'm a little confused about just intonation. Why are scales required at all?

I've read that you can design one just intonation scale which has a different 'color' or 'flavour' to another that is similar. Is this true? Can you play in a mode of it and still have your music sound good?

I've also read you can have many different chords, i.e. for minor it could be 1:1, 6:5, 3:2, or 1:1, 7:6, 3:2. These would both be minor, but different ones. Is this true?

The way I understand it, there are two types of transpositions. One is where you use the same intervals, but choose another note as a tonic. This means your music will sound the same, only higher or lower.

The other is where you use the same notes with a different tonic, which changes the intervals between notes.

Is this correct? I know in equal temperament, both of types of transpositions can sound good in the right place. Is the same true for just intonation?

So back to my first question. Why use scales? Is it because each scale has a mood, and changing scales changes the mood? If you can work out from any one note which notes will sound good with it, then you should be able to just use this rather than a fixed scale... is this true?

Lastly, i'd be interested in knowing if there is any software for composing in just intonation.

Thanks in advanced, any help would be appreciated. I'll check back here in a few days.
