This is cute, but it does require you to:

- maintain current rates in a configuration list that I4L knows about - the
telco won't tell you
- be limited only to LCR with carrier-select codes, so VoIP is not an
option.

So a setup to do it from Asterisk most certainly has its use. There may be
things to learn from the I4L sources in aspect of matching algorithms
perhaps (I don't know, haven't looked at them yet).
