I'd add a late_command that would automatically provide a well-known
public/private key for the eucalyptus user to all installations. Granted it's
not the safest thing to do, but for testing purposes it would help (this is
what I do in the puppet recipes).

I'd rather fire off all systems to install what they're supposed to be and not rely on having the systems to be installed in specific sequence:
  1. Install CLC
  2. Once CLC is installed, install CC+SC, install Walrus
  3. Once CC+SC is installed, install all NCs.

Automating the installation of multiple systems as a sequence is harder than
firing off all the systems at the same time and wait for the infrastructure to
settle (thanks to auto-registration).

The main usage of the option is to facilitate automated testing. There doesn't
even need to be a question asked. Having the possibility to preseed it is
enough.
