This is a really well-written, considered view of the trade-offs for using different options for security. I learned a lot from reading, and the plain language discussion of the topic allows most any reader to better understand the trade-offs present for each option. Much appreciated to the original author - it takes a good deal of time and effort to write something that lucid. Thanks.
