Yes - the Foundation is interested in ensuring FreeBSD works well in both virtualization guest and host capacities.
Newer EC2 instance types don't tie the Windows license fee to HVM mode and FreeBSD can be run on those, for no additional cost: https://aws.amazon.com/marketplace/pp/B00AA25MLK. The Foundation would like to see FreeBSD available on the other EC2 tiers without additional fees and is investigating alternate approaches there.
FWIW, while the AWS Marketplace only lists cc1.4xlarge, cg1.4xlarge, cc2.8xlarge, and hi1.4xlarge, my native-HVM AMIs also run on cr1.8xlarge, hs1.8xlarge, m3.xlarge, and m3.2xlarge.
The only instance types where you need to pay the Windows tax are m1., m2., c1.*, and t1.micro (although in some regions the Windows tax for t1.micro is free). Unfortunately, this set includes all of the smallest/cheapest instance types, and thus the ones people want to use most often...
I wasn't aware that Amazon had uncoupled the Windows license fee from HVM mode! If this is true, The FreeBSD Foundation should make sure EVERYONE knows about it -- getting FreeBSD to be a first-class citizen on EC2 is absolutely crucial if they want to increase their marketshare.
