Thanks again for all the advice! I decided to keg the beer. I siphoned carefully, leaving 1.5 inches of beer above the trub with the plastic part affixed to the end of the racking cane. That plastic piece fits on incredibly snug and I feel any particles of glass small enough to pass through this area will be trivial. We bottled the other 5 gallons in a seperate carboy which was not affected. I shook the keg to force carbonate and the beer is wonderful. My friend and I, both of us vividly aware of the details of the situation both enjoyed two pints. No glass was noticed. Just in case some particles should find themselves in the keg I'll waste a pint down the drain a week from now after it is totally settled.
It's funny. The owner of the homebrew shop in town agreed there was "nothing to worry about" and that "fragments big enough would be on the very bottom." He said, "People eat glass all the time" and we both had a laugh. Then I bought a brew pale for Mead Day tomorrow. I'll be getting some Better Bottles next month to replace my broken fermentors.
