I'd like to know what advantage your server folks find that SBS offers over Microsoft Office 365.
John, Office 365 is a great product. Using it along or along with Essentials is very helpful.
The difference is SBS is run on a server computer and allows one to run a domain. If one does not wish to have a client/server domain, that is OK. If they do not choose to use the capabilities, of which there are many, that is OK. P2P is fine. If you use Office 365, it still doesn't change the limitations of a P2P network (which, again, is fine).
Caution: Friendly sarcasem ahead:

Finally, some people don't like to use the cloud. I, for one, do not. But, again, it is a great product.
