Are Adobe fonts licensed for use in ebooks?

Can anybody confirm that Adobe fonts - specifically Minion Pro - are licensed for use in ebooks as well as print books? i.e. there is no need to buy the font twice - once with a license for print, and another with a license for ebooks.

I have a client who is prepared to purchase the font with an ebook license, but on MyFonts the only option is 'desktop'. I know the permission for the font is 'Editable embedding', but we aren't sure exactly what this means.

Many thanks in advance.
