Is floating IP (or CARP) supported when you use 2 FreeBSD droplets?

I would like to setup 2 droplets with FreeBSD 10, where the servers can act as fail-over for each other.

Is this possible?

Floating IPs seems to be implemented using a loadballancer, this means you'll be able to use it on any OS, the OS doesn't have to be aware of it, but the application should (sessions etc.) if possible.

You won't be able to use CARP.

How To Use Floating IPs on DigitalOcean
by Melissa Anderson
A DigitalOcean Floating IP is a publicly-accessible static IP address that can be mapped to one of your Droplets. A Floating IP can also be instantly remapped, via the DigitalOcean Control Panel or API, to one of your other Droplets in the same datacenter. This instant remapping capability grants you the ability to design and create High Availability (HA) server infrastructures by adding redundancy to the entry point, or gateway, to your servers.
