What about in an office environment?  My take-away from that paper
wasn't attacking servers, but laptops where people are likely to be
sending and receiving encrypted messages (like e-mail).

If this pans out, an attack path might go something like this:

laptop+GPG -> nearby smartphone on desk + surveillance malware that
turns microphone on -> RSA key compromise
