I guess the key problem is being able to generate and load arbitrary 
code. In JRuby, that would happen in JIT mode and if methods are bound 
using generated stubs/invokers. But we also can just run interpreted and 
  use reflection, which I think gets around the security issues. It 
seems like Groovy could do the same by precompiling, unless there's some 
additional code generation at runtime even when all code is precompiled.

It seems like CLR/DLR/Silverlight would have to support code generation 
to allow IronRuby and IronPython to run. Assuming that's the case, why 
is their security model more permissive about this kind of thing than 
the Java plugin's?
