I am positive that Pianoteq can be used in a live perfomance. I did it several times and was complimented about the fine nuances of the piano sound :-). The only drawback is that before a gig, you have set up your computer and the connection to the mixer, so you might need an extra 15 minutes to do that.
Layering of sounds is possible. The latency of pianoteq with respect to the other sound is acceptable and, I think, not audible. I did some measurement of the delay of the Pianoteq sound from various other sounds played by my instrument. I use a Kawai MP6, which has 4 zones. One zone sends midi signals into the computer, and another zone play a piano or guitar sound. Outputs from both the computer and the MP6 are sent to the mixer and recorded. The delays are in miliseconds, negative values mean that Pianoteq actually plays its sound before the MP6 does.

I think, in the worst case, you'll get something similar to the chorus effect, which is not so bad, I guess. But if you'd like to play a piano sound together with (slow) strings, I woudn't worry about the latency at all.
