I got a number with two lines from my VOIP company who happens to be my ISP.  I assume each VOIP company buys some numbers from some shadowy government organisation which controls phone numbers (ACMA?).  My number appears to be in Canberra where I live but I could probably get one that appears to be anywhere in Australia and if I went with an overseas company somewhere overseas.  I could have several numbers if I wanted.

It appears to everyone just like a normal number.

I don't believe you can but I could be wrong.

I've been thinking about this and have no idea.  It's nice and we're all used to having geographic numbers.  Perhaps we could have a group of VOIP numbers.  05, 06, 09? It's be nice to have free calls between VOIP providers but eventually when there are few POTS phones how will they make money?
