I don't assume that people have Visual Studio installed, I was just 
assuming that this DLL is present (which may come from elsewhere). From 
my experience, you end up having that DLL sooner or later if you only 
installed "enough" software, as chances are one of them was compiled 
with VC7.1 as well and installed that DLL in system32.
This also prevented any licensing issues I may have run into.

I found a MS article that said that this DLL is not considered a system 
component anymore and applications are supposed to ship with it if they 
need it. So I guess I should have included it (but it's kind of 
pointless having a *shared* library if every Python module that contains 
C++ code would have to install its own local copy).

Anyway, as Python 2.6/Python 3.0 will be out soon, I have to check if I 
will still be able to provide Windows binaries at all. From what I have 
seen so far, they are using a newer compiler and an initial test with 
Python 2.6b2 has failed (I couldn't even compile a simple "Hello World" 
extension module. The distutils just abort with an error but there is no 
useful error message at all. I suppose, it's because I'm missing the 
right compiler version)
