We do use ACE on LinuxRT (and all the rest of our platforms), as that's what LogosXT is based on. We worked with a customer to port TAO to PharLap a while back, and we even had it running on VxWorks. I'm not aware of anyone specifically using TAO on the 9068, yet, but it should be pretty straightforward. I don't have any immediate concerns that you'd have any difficulties. Both ACE and TAO are extremely portable framworks.
