Alexa communication with Echo Dot Outside USA

Echo speaks can be installed via HPM, but setting up the server is the tricky part. You can pay a fee and use the Heroku service, or use a always on computer/RPi to run it locally. You can do some speech stuff without using echo speaks or the other app mentioned using HE in conjunction with Alexa routines. Perhaps an example of what you want to do, and someone can chime in with a solution.
