Life, Liturgy, and Prayer

Thank you Richard for your post on Liturgy and Life and Tom for your post on Tony Campolo and the Spiritual Exercises.  Two questions directed mainly toward Tom, our Protestant readers, and those who know much more about such matters than I.  First, do Protestants (or subsets of Protestants) have similar fault lines to those described in Richard's post?  Second, have prayer traditions comparable to the Ignatian Spiritual Exercises or Carmelite Spirituality with its contemplative dimension developed in Protestant circles?
