I think indemnifying your customers from IP lawsuits when they use your product/technology isn't a bad thing.
It's the carrot at the end of the FUD. "If you buy our stuff, you'll be safe from someone suing."
"What's that, still going to use Unix? Well you'd better at least buy from Novell, as they've signed an agreement protecting you from being sued."
It's not "shades of SCO", it's the other side of the same coin.
