[infinispan-dev] EC2 Demo feedback

Pete Muir
Hi Noel

Generally, I was thinking about a new wiki page to complement the reference page i.e. a "Infinispan EC2 Example" page we could link from the reference.

(NB I spoke to Marek Goldman and he is publishing an AS6 AMI soon, that would allow us to very easily make these instructions more concrete).

Great, Marek did you publish the AMI we talked about last week?

Hmm, not sure of the best way around this, I think right now it's potentially a source of confusion to people.

Ok, let me try getting further :-)
