If I'm understanding this correctly:
1. The file must be restored to the very same computer that generated the backup. This is where our hangup is. If a computer gets stolen, melts down in a fire, motherboard goes bad, etc. - it leaves us in a situation where we have to shuttle a potentially large .enc file back and forth. If the SQL techs aren't around, it could mean big downtime - potentially up to two days. That's too onerous a burden.
I understand the security concerns, but I'd much rather deal with a password or something along those lines.
