The curriculum goes far beyond the knowledge of most IT professionals (not to mention our current graduate students), as it is focused on research; IT pros don't normally know much about, say, Python libraries for machine learning or signal processing.
They won't know how to use specific libraries, but they can sometimes help with things like how to install iPython on a Mac or Windows machine.
It does seem like some of this would make a good online course. There's some good stuff here http://faculty.washington.edu/rjl/classes/am583s2013/notes/i... which goes with the "High performance scientific computing" Coursera course, and of course there's the Software Carpentry site.
