What is the difference in hashing algorithm between bitcoin and litecoin?
Here you find an example, how to extract the data from getwork and call the scrypt function
http://litecoin.info/Scrypt

Unfortunately it is not clear (to me) what the resulting values of the scrypt should be. First I thought it is the result of the valid block above, but that has a different nounce.

If you find a valid result, please let me know the value.
