Dave,
Unfortuantely, I do not know of anyone offhand who has tried this. As I'm sure you have already heard, the is no support for the PXI-4060 in RT. The PXI-4070 is officially supported in RT, however. If someone does have any insight on this issue, I welcome them to post here and share their expertise. Good luck!
Sincerely,
Ross C
