Gert, hardware upgrades need to happen; otherwise we would all be stuck using bus interfaces designed in the early 1990s. Nobody likes paying for upgrades, but Cisco's 67xx line cards have been properly supported since 2003 - 9 years ago. If you bought them then on a 4Y depreciation basis, you would now have had 5 years of free operation. In a fast-moving world like networking, this really is unusually stable and a very good investment. Moreover, they still have good resale value. Re: DFCs, either you have distributed forwarding or you don't. If you do, you have much greater forwarding capacity. If you don't, your network will be cheaper to build. Shifting bits costs money.
