Hmm. Alternatively..
You could set a user-variable that shows they are on the trial.
Then, before you set the price, you check for that variable and if it's true, you set, say, nibble_rate=.02 and make sure they start with a balance of .01
You probably need to change the heartbeat to 30 seconds to do that.
Good luck :)

Call 30 seconds as a trial?
Perhaps skip nibblebill and use: sched_hangup
And count it somewhere that they used their trial period (using Mod_db with odbc  or mod_odbc_query from git contrib)
