perlbal use case question

[Michael Engelhart]

Hi Mark -

Thanks for the information and offer of help.

I'm going to continue brainstorming outside of the Perlbal box for  
now, knowing what it would take and that it  is most likely doable.    
You are correct in your assessment of my Perl knowledge though which  
doesn't go beyond Hello world ;-)

I'll post back here if I start digging into it though.

Thanks again

MIke
