One poster said he hacksawed a little bit of mountain handlebar then epoxied it inside his drop bars, this is what I plan to do as I find the Hubbub inordinately expensive.
Also, just an FYI in case anyone was in a similar predicament as me, I noticed Harris finally has pre-built 26" wheels for the Nexus 8 hubs, for about $300, less than if you ordered the parts yourself and had the LBS build them up, in many cases.
