Thanks Matt.
I REALLY hope that the C# client remains forever, or until Windows becomes a thing of the past. I know that you've put many hours and cash into the web client, but I fear that you may be trying to pimp out a Yugo. (sorry, that was the only analogy I can think of at the moment) However, if it is mandated I would suggest at least keeping the layout of the original client, and add/change things a little bit at a time as newer releases come out. I think that would help with the transition.
