How would you justify text in Silverlight?

Question

Does anyone have any suggestions on how to justify read-only text (rendered into a TextBlock) in Silverlight 2? WPF supports text justification by way of the TextAlignment enumeration:

public enum TextAlignment
{
    Left,
    Right,
    Center,
    Justify // <--- Missing from Silverlight :(
}

However, Silverlight 2 only supports the following:

public enum TextAlignment
{
    Center,
    Left,
    Right
}

Any ideas or suggestions gratefully received.

Off the top of my head, I can think of two not-so-easy ways to do this. One is rather lame; adding spaces between the words. The other would be to somehow parse the text so that each word is it's own text block, you could then use a Grid to left justify the first word of a line and right justify the last word of a line, then space the other blocks in the center cell using a stack panel or similar.

Determining which words are the start and end of a line would involve measuring the rendered size of each block and deciding if it will fit. It's not simple but it should work.
