[dba-Tech] Cameras etc

Hi folks
My brother in New Zealand has suggested that they and we buy cameras,
microphones etc for our PC's so that my nephews and nieces can speak to
us and their grandparents in the UK. My questions are along the lines
of:
- what would we need?
- is the techonology good?
- do others amongst you do this and how successful is it in practice?
- how much does it cost?
- any equipment recommendations?

that sort of thing. You get the picture I'm sure.
