Yes, actually I've determined that whether I use smbmount or 
smbclient, I can recurse until I get 40 directories deep in the share. 
  This is the case no matter how I do the recursion, so I assume 40 is 
hardcoded someplace as the max limit.

I noticed on page 1 of the wget manpage, 2nd P under Description: 
"Infinite recursion loops are always avoided by hashing the retrieved 
data."  Is this for some reason not applicable to smbclient, or would 
it be useful to add this, or should I be posting this to the samba 
developer list??

Do you mean in smbclient?  So currently thats not possible, you're 
suggesting it is useful to add such a feature/option?

I actually am using MySQL at the moment.  Indexing 100,000+ files with 
a text file (and doing searches!), well, yes that would be bad.

Thanks again for your help
