I was expecting this, and I expect that BRU will see a socket and deny as
well. Yes, it is a glorified GNU Tar program :), but I use it because it's
easier to point to a corporate entity when it comes to legal issues of
intellectual property loss. Quite frankly, I highly DO NOT recommend folks
using Tolisgroup's BRU. Their support is terrible. I went as far as the R&D
person, and he didn't think an upgrade would fix a problem. The support
people said it would. Go figure.

The whole rest of the operation uses opensource stuff. It's just the backup
that's proprietary. Pretty soon, I may be using AMANDA anyway :(
