[SI-LIST] : Dual Stripline impedance

Hi all,
We're thinking about using a dual stripline for a differential
pair. The diff. impedance should be 100ohm.
Have anyone used this before? Or seen it in suggested? Come to think
of it, it does sound like a good idea (not mine). Now, the hard part
is getting the right geometry... Any help from various programs or
books? Any references would very helpful, the only one I found is in
"Transmission Line Design Handbook", and it is not very clear. Can you
analyze this with a field solver?
The concept goes like this (cut-through view of the board):
Plane
-----------------------
--------
| L1 |
--------
--------
| L2 |
--------
-----------------------
Plane
The Zdiff should be between L1 and L2.
