But since the config file can't be dynamic, it's a little
annoying. Another easy option would be to use
Catalyst::Plugin::ConfigLoader::Environment and have people stick
something like this in .bashrc:

  export MYAPP_Model__AppDB_connect_info}='["dsn:foo","peanut","butter"]'

Or have a convention and stick this in /etc/bashrc

  export MYAPP_Model__AppDB_connect_info="['dsn:mysql:test_$USER','root','']"

But if you really want to do it dynamically in code, its probably most
easily done in your Model class; just override new and set the
connect_info to whatever you like.
