I need to send alerts to multiple phone numbers. Is it possible to do this with your app? For example, by including a comma separated list of numbers on the 'to' field?

You (or someone else might be able to) make a modification to bin/twilio.py to have it split into a list of numbers by comma and then making the API call for each number.
As it currently stands out of the box however, it seems that only one invocation of Twilio's API happens. As Twilio's documentation states that every recipient must be a separate API call, this would mean that out of the box you can only send to one recipient.
