You could do this within the FormHandler function, that you can pass to 
your form.

That will get an event with an action of something like 'add-row'. You 
can then query the form, count how many lines, and return false if you 
don't want it to add more lines.

See if you can work this out. If not, I'll dig out an example.

As to disabling, when I've done this, I've just passed everything 
necessary to make the decision as to whether or not to show a widget on 
into the stylesheet, so the stylesheet can then format the widget 

Make sense?
