The Census now *officially* works with Linux! ;)

The census online application now accessible to Linux operating system
In response to demand, Statistics Canada has removed the restriction
for Linux. This change takes effect May 13th, 2006.
This broadened access to open-source users is available to those who
have a valid browser and JVM. These minimum requirements are necessary
in order to maintain the same level of data encryption with Public Key
Infrastructure (PKI).
With the addition of this new operating system, the capacity of the
Census Help Line operators to respond to technical calls from open
source users may be limited. However, we expect this will not be a
major obstacle for the vast majority of these users.

Not sure what they mean exactly by the second-to-last sentence, but I
tested the site and Firefox on Linux now passes with flying colors :)
