Okay, I just went poking through the Tech Reports and found
Tech Note 203 which describes all sorts of ways to abuse the
Resource Manager. It sez that having too many resources 
degrades performance. I want to store the 2-3 megabytes in 
about 36-76 chunks. Thats about 100k per chunk. Is this 
"acceptable". Does anyone have experience with this sort 
of performance?

Thanks
