For those of you hosting your Grails apps on Amazon EC2, how are you
getting around the issue that the load balancers don't have static IPs
(and you can't assign an elastic IP to the LB)? So, therefore it's
not possible to assign a root domain (A record) to the load balancer.

I just use an apache EC2 instance to serve as my "load balancer" to N
tomcat EC2 instances and I'm not even using the elastic load balancer
(A record for root domain and Cname for www point to apache instance),
but is there a better way? With all the talk about BeanStalk (which
uses an elastic LB) as a great way to quickly host Grails apps, just
curious how others are circumventing this A record issue. Or are most
of your Grails apps simply on subdomains (and can obviously create
CName records to the DNS for the elastic LB)?

I found some questions on stackoverflow during my googlin, but didn't
think any of the answers were really conclusive, just hacks to get
around the issue. Please let me know your thoughts.

Thanks,
Bobby

Yes, you cannot today easily point the zone apex at the an AWS ELB because of the cname limitation. There is speculation (or just desire) that AWS will either provide some AWS specific approach with AWS Route 53 to have ELB's at the zone apex, or just allow Elastic IPs(static) for ELBs. 

Today we use ELBs for some grails apps because they are hosted at subdomains, but we do have a separate issue in some cases (e.g. reports) of another annoying ELB limitation where a idle connection is killed after 60 seconds of inactivity.
