If one was to develop an IDL application that used (for example) some python code via a bridge, and tried to distribute it using make_rt and the IDL virtual machine... I guess the end user would have to go through the process of setting paths and installing python just as I have been doing in the last few days? Seems a little tricky for the non-specialist... Are there plans to streamline the process?

Hi Will,
Is the IDL->Python bridge working for non-graphics? In other words, if you just do:
IDL> >>>2+2
Does it print out the answer?
If so, I'd suggest it's just a problem with either the Qt within Anaconda, or running Qt from within Python within IDL. I can't get the plot to show up on my Windows box either (I get a weird Qt error), although everything else works fine.
Regarding your "distributing software" question, we don't have any documentation or pre-canned solution for making this work. That's one of the unfortunate side effects of working with an open-source 3rd party package like Python - you sort of get what you pay for. Anyway, it's a great suggestion and we can think about adding better support in the future.
Cheers,
Chris
