Well, we got around to fixing it now that the weather is tolerable. It wasn't the front crankshaft seal and it wasn't the oil pump housing seal gasket either, so both your guesses were wrong.
It was the seal on front counterbalance shaft that caused the massive leaking. The seal had popped out from the oil pressure behind it and was riding on the shaft. There was no seal retaining fork installed, which I now understand was a recall on later model Accords. We replaced the front counterbalance shaft seal along with a seal retainer fork, the crankshaft seal, the timing belt, the countershaft belt and put in a new water pump just in case.
