Interestingly, the White House has ditched their proprietary content management system in favor of Drupal, another open source content management platform not unlike formVista.
As reported on Slashdot:
"WhiteHouse.gov has gone Drupal.
After months of planning, says an Obama Administration source, the
White House has ditched the proprietary content management system that
had been in place since the days of the Bush Administration in favor of
the latest version of the open-source Drupal software. Dries Buytaert
reflected on this, adding: 'this is a clear sign that governments realize that Open Source does not pose additional risks
compared to proprietary software, and furthermore, that by moving away
from proprietary software, they are not being locked into a particular
technology, and that they can benefit from the innovation that is the
result of thousands of developers collaborating on Drupal.'"
