Vocera Communications is dearly valued relative to its present level of sales and red ink has been flowing for several years.  However, 2015 has been a transformational year.  Sales have started to grow and the losses are attenuating.  A few years back it was largely dependent upon communications "badges" largely worn by nurses in hospitals, and it was challenged by new text messaging technologies.  With a fair amount of development spending and some well-conceived, financially reasonable acquisitions, we think recent quarters indicate it seems to be gaining traction on an enterprise level.  How is this affecting clinical systems, and is it improving patient care and streamlining workflow?
