spanning a split wim

[iamtheky]

when the WIM fits on one disc the following syntax is used and works beautifully

imagex /apply install.wim 1 C:
imagex /apply install.wim 2 D:
imagex /apply install.wim 3 E:

I would like to split this image in 2 parts for DVD install, I would be most interested in best practice for spanning swm files with multiple drives.

I would layout the fight I have had with imagex /split and createspannedshares.cmd, but all efforts were fruitless, so i figured best to start soliciting from scratch.
