Source Code of Voting Software

The other day I was reading about voting software and decided to get some more info about our situation. I encountered this:

http://www.ibz.rrn.fgov.be/index.php?id=1151&L=1

So I sent an email to CallCenterRRN@rrn.fgov.be asking where we can get the source code, as it is not available here.

The answer:

"The source code will be available after the elections."

_After_? Are they afraid it is going to be hacked if they release it before? This gives me a very strange feeling...
