I never asked about the assemblers, just Sleuth.  I got the impression 
that he was more intersted in seeing it used, than in any miniscule 
amount of money he could make selling it.

I'd have to go back thru my email corpus here to locate my last msg from 
Bud.  I have around 13 years worth, and I expect its been most of 10 
years since we last msgd each other.

Except that when I fired off the search, it reports scanning 1447 
messages, so my inbox housekeeping is good.  So now I have sent it to 
look at the coco folder which is a couple gigabytes.  And this will take 
some time. This is only a quad core phenom, but amanda is running too.  
My backup program...

Humm, 87324 messages searched for sleuth in the subject, pass in the 
from, and no hits.  Strange.  I'll send another search party out in the 
morning when I have a bit more of the machine to use.
