Hi Stephen,
All is pretty well. I hope you and the family are too!
HCI is being controlled to some extent in its roll out. It's more than a BETA release but it's not quite GA. Essentially SAP are trying to make sure they have the right resources available to support the initial implementations using HCI.
HCI is similar to Boomi but the one advantage I see is that this will be the go-forward integration technology for new customers and once that happens (I hear in H1 2016) I foresee Boomi no longer being offered to new customers.
All the best,
Luke
