Heh, I don't think it's possible to include two versions of libc6 like
that...Maybe using LD_LIBRARY_PATH or LD_PRELOAD or so?  Try the ld.so
manpage.

Sure...

If it was me, I'd just create a woody chroot and use that for all my
linking needs: http://people.debian.org/~walters/chroot.html.  Pretty
simple to do, and it'll let you run everything on the same machine.  Or,
if you're creating Debian packages of your software (not necessarily for
re-distribution, of course ;), you could use 'pbuilder', which greatly
simplifies this process.
