SMSCast is a group messaging solution using txtweb + Google App Engine.
What it can do
SMSCast will read messages sent by anyone from a registered userbase and re-broadcast it to that userbase
SMSCast is pretty useful for small groups that can be used to quickly convey information.
There is an inbuilt check to ensure that messages come from txtweb and mobile phone numbers, and are not exploited on the web by spammers
txtweb imposes a 5000 PUSH text messages per day limit. This means the app will be able to send 5000 messages in all to the group, not individually
- Impose a 5-messages per hour limit for each user to avoid unnecessary spamming
- Add a master switch to disable group posting in case it is ever compromised
