I keep reading that SMTs are easy to set up, even for entrepreneurs without developing skills...

We are not there yet, right now only developers can play around with the code (with the testnet). Once that phase is complete (which can take months) and the witnesses are confident that it's safe to deploy the code in a live enviornment then we can talk about setting a date for a hard fork and develop the user interface(s) where it will be "easy" for non-developers to setup an SMT.

In the meantime those of us without developer skills will have to wait.
