It's great that we now have the BCP lectionaries (both Sunday and Daily), but how about the Book of Common Prayer itself. Either the 1928 edition or the 1979 edition, or preferably both!
I'd particularly love to have it available in Logos for when I'm planning worship. I don't go to an Anglican or Episcopal Church, but we often like to borrow prayers and liturgical elements from other traditions, and the BCP has some of the best.
Someone has put the 1979 edition online here: http://www.bcponline.org and there are various editions of it here and here.
