Re:Texting vs. Hubble (Score 1)

The texting cost calculations might be missing an important point. You probably don't have to 'provision' any (or much) bandwidth specifically for texting. Most of the time, when the 'pipe' is not already full, you have 'excess' bandwidth available for texting. You probably design your system to handle peak demand (uh, actual calls, and data/internet), which ideally is never quite met or exceeded in practice. That's assuming that the proportion of bandwidth eaten up by instant messaging is tiny, though.
