Bezier stuff

Hi, been looking at bezier patches with the aim of making a 'landscape' editor.

I've done the standard bezier patch (4 by 4 control points) and it works ok but to do a landscape would need patches 'joined up'.

1) How easy is it to make the joining of edges smooth?
2) Would it be possible to do variable sized patches?

Thanks
Marg
