Is there a way to specify that a calt feature be turned on by default in say, illustrator and indesign?
In general, in InDesign, you can set your defaults by choosing them when nothing is selected -- with a document open you're setting the document defaults, or you can choose OpenType features to be on by default in a no-documents-open state which will copy these defaults to all new documents. However, I would recommend a style-sheet based workflow. There is a related thread about OpenType features going today as well.
