SPI Between 'Arduinos'

Would you mind sharing your final SPI Slave Code for the Attiny?
The code sniplet on the previous page did not work correctly.

If not, maybe you could take a look at
http://arduino.cc/forum/index.php/topic,126771.15.html
and have a look at my code snipplets. I cant get them to work.

Many thanks in advance,
Jan
