I can't speak for Stanford, but I pursued a BS and MS simultaneously at Cal Poly. Cal Poly's computer science department has a 4+1 program that lets you start taking graduate courses while you're finishing your undergraduate degree. The program also drops the senior project requirement for the BS and combines it with the master's thesis required for the MS.
