Are you talking about this?

If I were to purchase the OTF version of this font, would I be able (fairly
easily) in ConTeXt to typeset my entire document (text and math) using the
sans serif Helvetica font?  Is that something that would have to have a
great amount of work done in ConTeXt to setup, or is it "ready to go" since
it's in OTF format?
