I added a new session storage backend for Dancer2 today. Dancer2::Session::CHI is on its way to your local CPAN mirror. If you are currently using CHI in your Dancer2 applications, this will let you use CHI as your backing datastore for storage data. Please see the pod for details. Contact me with any issues you may have, or file them on the github bugtracker. Thanks! Happy Dancing! Jason / CromeDome
