after up2date -u failed (there was enough room to fetch the rpm's but not to 
install them) I freed up some additional space and ran up2date -u again.  The 
basic problem is that the "total size check" @ line 1007 of wrapper.py 
 
    for pkg in selPkgList: 
        totalSize = totalSize + int(pkg[5]) 
 
doesn't factor in whether the pkg is already cached locally or not.  Hence, 
I'm in a situation where up2date says I don't have the room to  transfer the 
rpm's even though they're sitting in /var/spool/up2date/ 
 
At least on first glance, though, whether or not the package is cached on disk 
is so buried that I'm not sure wrapper can easily get that info, but I could 
be wrong - if it's exposable it should be an easy one-line hack to if 
(!cached(..)) it @ line 1008 of wrapper.py, I'd think
