Load balancing IPSec over multiple WANs

[lboc]

Hi, we are using pfsense for connecting some of our branch offices. Is it possible to get redundant AND load balanced IPSec tunnels over multiple WAN:s?
It does not necessarily be IPSec, as long as the VPN connections are secure enough. Any ideas?

(I have searched the forum but do not find any good answers)
