Hey kayrus.
I tested cloud-init on FreeBSD 10 and can tell you that bsd-cloudinit does not support NoCloud and ConfigDrive datastores. For my project I used cloud-init 0.7.7 (it does support FreeBSD, but not in official way).
Just need to disable "sync" mounting by default and add distro password changing method.
If you are interested, please let me know and I'll share my investiations.

[kayrus]

sure. I test lot of macos related stuff in freebsd. and I have to recreate freebsd VMs quite frequently. sshkeys/network configuration takes a lot of time

Unfortunately, I didn't fork cloud-init on github and can't show you code examples, but I am planning to do this.
So, here are changes, that I made to cloud-init 0.7.7:

1. make password changing disto-specific

2. comment sync mounting (I am sure there is a better way to do it):

Here are steps to install cloud-init package on FreeBSD 10:

1. install python setuptools (AFAIR, package name is py-setuptools)
2. install package e2fsprogs (to use blkid)
3. install cloud-init python2.7 setup.py install --init-system=sysvinit_freebsd
4. by default installer brings you cloud.cfg for ubuntu although there is config for FreeBSD, so be sure to check /usr/local/etc/cloud/cloud.cfg for proper options
5. on FreeBSD config files from /usr/local/etc/cloud/cloud.cfg.d does not work (I did not manage to guess why), so to use proper logging you should move logging settings to main config
6. To minimize cloud-init datastore searching time I edited datastore_list in config and left only preffered datasources (NoCloud and ConfigDrive)
7. Finally, you need to activate cloud-init in /etc/rc.conf: cloudinit_enable="YES"

I use static network settings in meta-data file with NoCloud and it works perfectly, renaming interface and commiting settings in /etc/rc.conf. But there is one little problem - on first boot after customizing routing does not start, so I added command /etc/rc.d/routing start to runcmd.
Root user password changing and ssh key commiting works too. Didn't try other functions like package installing though.

i'll test these changes this week.
p.s. There should be a way to propose these patches to freebsd developers.

[merovigen]

I used cloud-init from launchpad, not from FreeBSD ports.
Actually, I didn't know there is a port for it) So I'll test it too to see the difference.

EDIT:
checked freebsd port version of cloud-init 0.7.6
There are the same problems, starting from blkid utility missing and to the config problems.
