Check implementation of packaging mechanism in
"eShipper Integration Module for shipping with Canada Post, UPS, Fedex, Purolator, DHL and UPS v2.4"
(http://addons.oscommerce.com/info/5711)
I created pluggable mechanism for hot-swap of packaging algorithms and two of them are "packing in single package" and UPS style.
Packing in single package is probably what you need now. Just rip it out from the rest (it's encapsulated class) and replace default UPS mechanism.

I ship a lot of small items. The ups and usps modules work great but will calculate a seperate package for each item,
and the shipping charge is to high. I would like to be able to combine certain products by product name and /or
quantity into a single package. I looked through the forum but didn't find anything that looks close to what I need.
Thanks
