Could IP just ignore the timestamp on ironpython.dll and let the .Net runtime 
figure out if there are any references to no-longer-present mechanisms within 
the binary?

Keith, is it really the case that your clients without Python source are going 
to download new versions of IP and (this is important) put them in the 
directory with your software?  That is, assuming that you put IP.DLL in the 
directory with the EXEs/DLLs you built, even if they're doing their own IP 
development elsewhere on the machine and updating it regularly, won't your 
executables use the old IP.DLL until you give them the new one (and presumably 
matching recompiled EXEs/DLLs)?
