Thanks everyone for the input and advice.  Especially for that ScanCalc 
tool - it's quite helpful since it really does account for viewing 
distance.  I'm curious as to the formula(e) being used, though.

Here's what I'm thinking I'll try:

35mm frames scanned on my Nikon IV (pushing it a bit at 2900 dpi, but 
according to the ScanCalc program I should be able to get all the way out 
to 65"x44" at a 3' viewing distance.  We'll see how accurate that is...)

120 frames scanned on an Epson 3200, at 1600dpi and 3200 dpi.

both formats drum scanned (assuming work will pay for that service for me 
to test).

I will try both negatives and slides, just for the heck of it.

I'll use Qimage for all the printing and interpolation, since I'm familiar 
with it.  The only question is how much RAM will be enough for all these 
scenarios.  I have no doubt we can get at least 1GB in there, but I'd like 
to get 2GB or even more.

thanks again,
allan
