Probably, although I'm not looking at doing any volume, just wanting to
experiment. There are a couple of suggestions in those comments like
adding the zener diodes present in the original design or slowing down
transfers.
The USBasp looks interesting, and it has those zener diodes, but some
comments said it had trouble with USB hubs.
There are also several ways to set up an Arduino as an AVR programmer,
and the additional cost over the USBTiny is low. The FTDI USB chip on
an Arduino should be pretty robust. Certainly FreeBSD can talk to it.
