This is not the big problem here I think (Python has an rshell). Whenever you
distribute code (generated or not) you implicitly rely on a sahred
body of support
code. This is exactly the problem with Java. Its relied heavily on the libraries
rather than just the machine. I cannot yet see how we could generate something
that was usable apart from the FEniCS framework, in which case the user was
able to install, so why have a webform at all?
