Currently Floating IP feature is of very very limited usefulness. I can connect to web and FTP resources but UDP ones fail. Presently a droplet has no way to send data from it's floating IP address, which means it fails in some areas.
I would like to see the floating IP system get boosted up a bit to make the floating IP an additional IP on the droplet, so that it will act as a fully additional IP on the droplet. Thus, it will allow that IP to be fully utilized and provide more scenarios where the Floating IP system is useful.
