Eldar - The OpenStack API already supports sharing IPs between instances (although this may be an extension?). What exact behavior are you after? More important than the way in which we expose via the API is how it's implemented. It's important to note that this is extremely network topology dependent. Sharing IPs today requires L2 adjacency so other VMs can GARP for the IP. L2 doesn't work at scale so you need another mechanism. I'm pretty sure the way AWS does it is to have a separate pool of IPs and inject /32 routes higher up that route towards the appropriate VM IP. What are your thoughts around how this would be implemented?
Multiple people are working towards an independent Network as a Service external to nova so it may make sense to plug this requirement in there.
