[thelist] Open Source Shooping Cart with Good Quickbooks Integration

[Rich Points]

Howdy,
I'm doing some research for a client on shopping carts.  One of the main 
features they would like to have is strong QuickBooks integration.  I've 
checked out Zen Cart which seems really cool but I haven't found a 
QuickBooks mod.  Is there one?  Does OS Commerce support QuickBooks?   
Are there others I should be looking at?  It doesn't necessarily need to 
be Open Source.

Thanks
Rich
