Just got an email from one of the hobohookah guys:
Thanks for the love and glad you're liking the Hobo! It is great when people share their thoughts online - helps us improve and helps people determine if this wild cat of a hookah is right for them.
We are working on incorporating an exhaust into our next model - this is by far the most requested feature and not including it was admittedly a poor choice on our part. HoboHookah 2.0 is hopefully coming out sometime this year, along with a basic model as well so we can better compete with the cheaper part of the market.
Thanks again and definitely let me know if you put out more videos.
Looks like good news on all parts!
Oh hey, I got featured on their blog with a shout to HP, too: http://hobohookah.com/blog/
