The intent is to allow the IP protocol suite to be supported over an InfiniBand fabric - there are many usage models even with an InfiniBand only solution (this was covered in the first BOF to kick off this workgroup - not sure where those slides are posted but might be a good background reference). This can be between two endnodes, e.g. a set of servers, or between two devices, e.g. an IB-to-IP gateway where one links an InfiniBand connected set of endnodes with another fabric type (e.g. Ethernet) and provide IP routed packets between the two domains.
