Here, the University has a deal with an academic consortium to provide
cert.s chained back, ultimately, to a well-known commercial provider.
I just submit a CSR to a website, a globally-valid cert. is issued to
me in a few hours, and my department is not billed for anything.  It's
probably cheaper than all the paperwork required to process a
requisition and chargeback.

We use this, not only for email, but for websites and other network
services, where there is no viable OpenPGP-based alternative.  The
ability to issue email certificates was actually added later, when the
Powers That Be became increasingly concerned about phishing.
