In a related vein, I've seen it noted elswhere that DLLs and font description packages are considered COTS items for source code inspection purposes. In otherwords you could change a DLL that a voting program uses and not have to have the program re-certified. This obviously violates the spirit of code integrity and seems dumb to me.

Thus it seems philosophically that as much code as possible should be statically linked.

Given that does it matter if one is using a high-level object or re-implementing the functionality from low level commands. If you are statically linked this is effectively the same as having copied the source code into the main program. It's static and as long as you dont update the library you compiled against it wont change.

  The difference only appears when you update your widget libraries; you could inherent new properties and not realize it. I think that is the concern you are getting at correct?

I should note that Fred McLain has made the argument that the GUI
ballot application should eschew the use of widget libraries such as
wxPython of PyQt. He mentioned this on the telephone, and in email;
I'm not sure if that email went to the OVC-Dev list, or just to a Cc:

The current GUI app was designed and written by Jean-Paul Gignac using
a library called PyGame. This approach basically takes a fixed image
of the ballot for a background, then responds to clicks in certain
regions of the screen. This bypasses the use of high-level widgets
like radio-buttons or pick-lists.

David Jefferson's security concern seems to promote the continued use
of a similar programming style to that Jean-Paul and Fred chose.
