What did you do with it?
I'd say this is a timely example of the "Ideas are worthless. Execution is everything." mantra from just the other day.
we are working on international support, stay tuned
Here's a related example which I'm busy coding today: I wanted people to be able to record custom appointment reminders, but (following many years of supporting non-technical users) think microphones and MP3 encoding are probably beyond their ken. So instead, when you click "Send Mary Smith a custom reminder" on the site, it pops up a lightbox saying "Call 555-123-1234 and type in the code 1234", and when you do so the phone will say "Leave your custom message for Mary Smith's appointment on June 16th from 5:00 PM to 5:30 PM after the beep." Then, after doing so, your lightbox automatically closes and you get visual indication of success.
Bonus points: registering new numbers in Twilio is so cheap that I can trivially afford to give every customer their own call-in number, and tell them to put it on speed dial. Then I can use the same basic pattern for any number of tasks.
Amazon does this as a confirmation step when you sign up for AWS, and most of the interactions in Google Voice are based on this model.
At my place, I have a group ("Gate") set up in Google Voice which forwards the number to my cell phone and if I can't access my phone, then the custom voicemail that caller hears is the DTMF key ("9" in my case) sound and so if I am not able to get the phone, it will automatically buzz them in.
Food for thought. Does anyone know if Twillo does sub-one-minute billing?
I can report back on how much it costs me to run this thing after a month. With 5 people coming and going average of 2 times per day each, I expect it is going to come out to around $0.30 per day x 30 days plus the $1/mo for the phone number -- so roughly $10/month... we'll see how close my guess is
