Let me give you the skinny right from the horses mouth. Here's what I did:
I was using a laptop (P4 ~2GHz) with a FireBox. I set the FireBox to 6ms on the FireBox control panel. This could probably go lower on a more powerful machine. I then set the PowerSDR buffers to 512 for the Audio and DSP. I set the FireBox and PowerSDR to use 96kHz sampling rate. At this speed, our prospective customer was able to send 50WPM using the soundcard monitor (not an external keyer). This is the first time that we have tried this experiment at high speed since we added 96kHz support. Previous attempts at this speed all led to us directing our customers to use external keyers for high speed CW. The long and short of this is that with the right setup (small buffers, low latency, fast PC, etc), high speed semi-break in CW is possible with the SDR-1000 TODAY!
