Perhaps not surprising, but I'm definitely in agreement with Joe
regarding having multiple keys when possible and (reasonably)
straight-forward to do so.  I also don't buy off on the OpenSSL
argument; their more severe issues certainly haven't been due to key
management issues such as what we're discussing here, so I don't think
the argument applies.

Thanks,
