Tankless On Galvanized Piping?

What is everyone's opinion on the viability of installing a tankless water heater in a home that has mostly old galvanized water supplies? I had someone ask me about this recently and I said I wouldn't recommend it. It seems like all that unavoidable rust will destroy the heat exchanger even if it's flushed a few times per year.

Has anyone had success or nightmare with this scenario?

Re: Tankless On Galvanized Piping?

How about a filter on the cold water in side, one that could be inspected and cleaned/changed periodically?
