As the caQtDM web page says:

          Kasemir,

      thank you for your answer. Let me tell our story:

      We saw in CS-Studio a good opportunity to beamline's staff to build
their own screens because of the user friendly interface. The problem is
that beamline's staff are full of good idea and desires, but have poor
programming skills. So, we prepared a 2 days course as they could start
to use CS-Studio in a basic way. Even with few programming skills they
could build beautiful and useful screens to use the IOCs we developed
for them.

      For complex tasks we created a python framework called py4syn that
they use in parallel with CS-Studio.

      The problem is that some of them adventure themselves to develop
complex python scripts and embedded them in BOY widgets. The result is
that sometimes CS-Studio freezes because of script issues and the
biggest derived problem is that their wrong perception is that CS-Studio
is not a good tool. This way, two of our beamlines decided to migrate to
MEDM, even when we tried to show that the problem was not caused by the
tool.

      For us in LNLS it is a good strategy to give some freedom to
beamline's staff to build some pieces of software in the EPICS client
layer, but due to lack of programming skills we don't think it's a good
idea to allow them to build their own IOCs.

      I agree that the best way to work is not to put those scripts
inside BOY, but could I suggest to put some protection mechanisms that
allow CS-Studio to run smoothly even if an embedded script runs in an
accidental continuous loop?

      Thank you again,
