[Zope] acquisition context within product method

[Richard Rosenberg]

Thanks again Dieter. . .

Shortly after sending that last message I see the error of my  
ways. . .I have moved the relevant operations out of __init__ and now  
they work (sort of). I guess it is important to know precisely where  
you are at the moment when it comes to Zope acquisition. . .duh.

Now it's off to the races (the turtle races anyway) and I'll post how  
this turns out along with some comments later. I'm presently accessing  
the methods of a zpsycopg DA to retrieve the table names contained in  
the underlying database. . .woohoo. If most of the DAs are similar in  
their structure, the rest should be relatively easy.
