No, i don't think this will work very well in practice at all.
it'll be better than nothing though.

Yes... which leads to using the IMQ device as Andreas said.

There are no 'aliased' IP addresses. This is just legacy ifconfig notation.
All IP addresses are treated the same on an interface - so yes.
