[oclug] named pipes and grep question

[Mike]

I have a script that will generate all 9 letter combinations
After half a day the output is at 36G and it has only gone from aaaaaaaa to 
aamkvcuuh.  So I do not have space to generate all the possible keys.

It now looks like the finished file will be > 24 TB.

So I'm thinking a named pipe might the be solution. 

>mkfifo testlist
>mkList > testlist
>aircrack-ng -w <testlist  

How closely matched do the 2 ends have to be in processing speed?

It has taken almost 18 hours for air crack to get to aaabmzqmo so it is a bit 
slower than the script 

Will nice be enough to adjust the speed?

I've learned that it contains valid english words
Any ideas on a grep to remove invalid letter combinations?
  such as > triple letter combinations  like aaa, ... qqq,
