1 can be done via the API
2 would be within your VM, adding a virtual host to your webserver config or whatever. that's not something that'd be handled by linode's API, but it's definitely something that you could write code or script to do

Fine thanks!
Answer 1 opens some very interesting possibilities (comparing with what was able 5 years ago)...Now let's see what API has to say (curl based?)...
Answer 2 should be obvious to me! It's linode's DNS servers that do the work sending requests to client's box; the rest is handled by Apache's virtual hosts etc...thanks for your time.
