Can 32-bit and 64-bit Java be simultaneously installed on Vista x64?

Yes, and in fact, this is the only way to get Java Webstart, as there is no 64-bit version.

Edit: Supposedly a 64-bit Java WebStart will be available in Java 6u12.

Considering that when you update Java, it never removes the old version of Java, you should be able to run 32 and 64 bit java at the same time without a problem.
