The Plan
The overarching goal of Soprani.ca is to seamlessly bridge the phone network to standard text/voice(/video) protocols so users have at least as much functionality but with far more flexibility.
Once we've achieved that, then we should be able to convince everyone to switch to the standard protocols (since they can seamlessly communicate with those not (yet) using the standard protocols) and turn off the phone network. If we can't convince them, that's probably an indication that the goal hasn't been achieved (ie. the phone network still has features that we haven't yet replicated with standard protocols).
