# Typesetting a tricky matrix in LaTeX

I am trying to typeset the attached partitioned 8x8 matrix in LaTeX. I have drawn it without the parentheses with the columns and rows numbered. Submatrices I, 0, A, B, C, and D are 2X2 matrices while T is a 4X4 matrix. The main trouble I have is getting T to span the rows and columns. Is there any elegant way to do this in LaTeX?? Thank you!
