Very interesting, although I usually rename all those (IMO silly) Windows type filenames with spaces in them.

I do so as well. It's more a GUI than a Windows problem.

Now what about two spaces in a row? Just curious.

I tried and it seems that there is a severe bug in pdftex.

\input "foo bar"

It would be a severe bug if the documentation said this would work and it did not, but that is not the case. As it stands, this is a documented limitation: multiple consecutive spaces are always collapsed into one. There is no easy way to extend pdftex, because the token scanning routines do not know exactly when a filename is being read. Consider, for instance, \LaTeX's \include command, that accepts a filename as an argument, and could itself be part of a macro expansion. That said, pdftex *can* read files with multiple spaces in them, if you are able to intercept the tokenizer fast enough. either \catcode`\ =12\relax\input"foo bar"\catcode`\ =10\relax or {\catcode`\ =12\gdef\notaspace{ }} \input"a\notaspace\notaspace b" works fine.
