To me, DMV stands for Department of Motor Vehicles.
DelMarVa is the geographic peninsula east of Chesapeake Bay and west of Delaware Bay.
The ring of urban sprawl around the federal capital is "The DC Area". Unfortunately, "DC Metro" is the train system, and "DC Metropolis" is where Superman lives.
The only (well paying) tech jobs in Delaware would probably be working on internal systems for credit card companies in Wilmington. Possibly also registered agent software for CT or CSC, or some other business revolving around corporate registration and reporting.
I can't help thinking "Columbia Metropolis" would be a better name for the urban areas around the District of Columbia. But I don't have the authority to just change the names of things.
Richmond is several hours away from the DMV metro area. It's... alright? But I wouldn't call it a metro area. It's more like a college town that has a foodie and music scene, and of course is chock full of history, being the national capital of the Confederacy and instrumental in providing support for the American Revolutionary War and later industrial power.
