We got into a discussion of nomadic versus mobile and how a nomadic device such as a laptop is not necessarily mobile while a mobile device is nomadic. Yes, these are the sorts of conversations engineers have amongst themselves when no one stops them.
Getting back to my original idea, many companies in the VoIP space focus on the device while BlueNote is device agnostic. Communications has to work with not only mobile devices but nomadic ones such as laptops. Using SOA, communications needs to be embedded into applications not just an adjunct. That is the world according to BlueNote.
It should be further stated that some of the other companies in the p2p space such as Nimcat which is now Avaya and Popular Telephony do some similar things and also focus on embedding their technology into phones. This latter idea is not the BlueNote view of the world.
