Getting something up and running is trivial and only takes a few 
minutes. Getting something with the same features as OTP but without the 
cost? I hope you got a lot of free time.

Of course you can probably cut a certain amount of features out, few 
people use release upgrades for example. You can probably cut out the io 
server and other features related to distribution if you're making a 
single-node system.
