Logic Pro 8 Exporting rewired tracks in Logic.

How do I export all tracks included the live and reason rewired tracks? I have 2 tracks in Logic, then I got 10 in Live and 2 in Reason, but when I try to export them as "all tracks as audio files" I only obtain the Logic tracks as final result.
I use Logic 8

thanx a lot
AFAIK, Doug is right. They have to be recorded in real time. Something to do with the laws of physics :)
At least ReWire returns from Reason can be bounced offline. I have to admit I was somewhat amazed when I saw for the first time that this works:)
