Going forward I expect that most sites will migrate from medm/edm to either CSS or caQtDM.  If BCDA discontinues medm support, then synApps will be supplied with only caQtDM screens?  This will leave CSS users with no way to convert synApps screens for their use?  I ask because I am also trying to figure out the best way forward for areaDetector, quadEM, dxp, mca and the other packages that I support.  Being able to quickly utilize a new PV that is added to a module with the display files provided in the distribution is useful.

The workflow BCDA is using to support its beam lines at the APS to 
transition from MEDM to caQtDM is

1. implement on-demand scripted conversion from .adl to .ui files
2. beam lines to use caQtDM when screens are ready
3. continue to edit screens as .adl files during transition
    and convert to .ui (choices managed by a Makefile rule)
4. train facility staff to use Qt Designer
5. edit screens in Qt Designer
6. discontinue MEDM altogether

Hope to complete that by spring 2017
