Unless you are prepared to use a system like a Stratus and co-locate the machine in a telco-grade facility complete with generators, I wouldn't promiss "NEVER." A fully (99%) reliant system, figure 10K per month minimum for service and 250K minimum for hardware. Now, if what they want is a "better than the other guy" setup, yeah, you could do that with mirrored systems but you'd better be multi-homed because even UUNET has semi-regular outages. Good luck and be careful what you promise. Even NYNEX frame relay which is about as reliable as it gets was out twice during the last six months. (One time for nine hours) BTW: Considering most people connect to web servers via flaky modem dialups, it's kinda pointless to build a excessively high availability system for general public use. Now if the client is Fidelity Investments, well they'll spend millions just to keep Lotus Notes running!
