You're assuming they're only sending from one phone number.
Hrm... that's probably how it would work in most cases, as it would be confusing to end users to sign up from one number and get a text from one they don't know about (even if the footer text indicated who it was from).
This pricing issue is one of the reasons I could never justify pressing forward with my initial idea of getting in to this market. Someone will end up being the "constant contact of sms" - that seems a logical market to pursue, but I'm not sure how to get there with the current pricing models (I mean in general, not specifically sendhub).
This is the major disadvantage of using longcodes (regular 7 digit phone number) and is the reason that any company that is serious about sending out large quantity of messages, is using a shortcode (5-6 digit number) which can (with twilio) send up to 60 messages per second.
