Thanks, spec. Yes, there were so many aspects of the various processes the different technologies used that DDI could help with. But you're right, I guess they can only be in so many places at one time, and they're obviously keeping busy; sounds like you would agree, though, that if wave technology ever matures, DDI would be right there with needed (and already mature) products/services, so this is yet another definite potential application for their technology beyond oil.
