fai remote install ubuntu

[linux-service.be bvba]

I am able to run for example paterdmagic on a ubuntu pc(enry in grub pointing to a iso and completely loaded 
in ram).I can access this live partedmagic with an ssh tunnel.With partedmagic the main hdd is not mounted.
Can I use fai iso to do the same : make an entry in grub2 on the ubuntu pc and boot in it, than install a 
newer version of ubuntu on the hdd. Fai should be accessable with a ssh tunnel however to start the 
installation.
This way I shlould be able to install a new distro on the hdd remotely.
Is this possible?
