Not just Yahoo. In the weeks before and after the DTrace conference in
SF, I did presentations at Nokia, Ironport (Cisco), Juniper Networks
and Isilon.

I also gave a talk at the BSDcan conference in Ottawa last month.

The next arch port for DTrace on FreeBSD is MIPS. Thanks to MIPS
Technologies for (promising to) send the hardware.
