There are some builders working with steel offering custom geometry full suspension bikes. Marino and Terraplane are two I know of. Steel is inherently more heavy which makes it difficult to integrate more complicated suspension systems without adding weight. Maybe the benefits aren't as much for shorter travel bikes.
