Down with PoIP

Voice over IP, a field I've been working in, has been generating some recent excitement. And that's appropriate.

However a lot of the talk is about something I consider the wrong direction. I call it PoIP, for PSTN over IP or worse, POTS over IP. (POTS, in turn, stands for Plain old Telephone Service.)

Support public/private in 802.11 access points

Almost everybody has a WiFi (802.11) access point these days. Some leave them open by accident, some deliberately, some turn on encryption or other security. Being open can be nice to neighbours and wanderers, though it can also be abused, and if you have insecure machines on the local NAT, it's risky.
