The short answer is yes, but what I'd also like to address is doing business cases on all these situations, and that's a discipline we're trying to instill not only in ourselves but among the community, to not walk into situations and simply assume. Very large assumptions can really take you sideways. In the case of VoIP that you're bringing up, yes, the savings, both qualitative and quantitative, are enough to go in that direction because, inevitably, everything wears out. At some point you have to replace cable, people will move among buildings, and in those cases you have this three-dimensional chess game going on, parts always in motion. The idea that you're getting ready to move 300 people from this building to that building, and they're otherwise doing a retrofit, and now we have an opportunity to support the blueprint 2020 objectives of the government, so instead of putting in an old-style telephone line and a new-style digital line, you put in one cable that supports both. There are advantages.
Then there's also security, management opportunities, flexibility.
