Yes, I was wrong. I just looked it up in the datasheet. Above 12MHz the maximum 
ISP clock is f_ck/6 - so you are already faster than it should be possible ;)

Ah. PCB traces are the better cables - if routing is good. You can go even 
faster than the datasheet says ;)

Yes, but only in the config file (avrdude.conf) set usbdev to A or B (both 
upper case and lower case is valid).

I don't know. I guess there are no "official" build for any system. Third 
parties might provide binaries, but I don't know any.
