Web Insecurity: Security Costs vs Benefits: Should companies deploy SSL to deal with Firesheep?

Yesterday, I talked about why end-users don't care about security and how that actually makes a certain amount of sense for them since the cost of behaving more securely can overwhelm the cost of an actual breach.
