Hello Chris,
I found your post very interesting as I do like problem solving! As I understood your comments you would like to hear both Bösendorfer and Pianoteq sounds simultaneously.
Audio interfaces have changed significantly over the last three years. Laptop manufacturers have abandoned fast bus based audio interfaces that use Firewire, Cardbus and Expresscard for a simpler and less costly (for them) USB solution. The manufacturers of audio interfaces for laptops have followed this trend and, for laptops, only offer USB versions of their audio interface.
Much hype is provided by manufacturers about their USB products having 'almost zero latency', i.e. from the time you hit the key until the time you perceive the sound. They have got very close to achieving this but they do not mention the delay caused by the PC's internal processing time of a USB input to audio output. this can be a total of 6.8 milliseconds. If all you are doing is listening then this time period may be acceptable but if you are trying to synchronise that sound with your Bösendorfer live sound then beat frequencies are most likely to be heard.
A faster way to handle sound in a laptop is to use a Firewire (IEEE1394) interface or an Expresscard interface (which I use). Much depends on the model of laptop you currently use. My audio card is an Echo Indigo Expresscard:

This has its own ASIO driver and provides 24bit processing, i.e. higher than CD quality
I'm using it with Pianoteq and very satisfied. Unfortunately my acoustic piano is downstairs so my present digital setup is not around to test the bi-acoustic "aligned" sound performance of both but I'll soon be able to do this and will post my findings.
