Of course, but SVG is a tool, so if it's relevant tool to the market, we should discuss it, and ensure that it meets the needs of that market, SVG-Mobile does this (well maybe, there's some debate it would seem, and I personally despite being a high mobile data user would never use something smaller than a PDA for accessing content and I'm not a developer in the area I couldn't really judge - IVR is as close as I get.)
