I don't really understand what one actually means when one says about doing string theory in a background independent way.
Apparently B. Sathiapalan is the only person (as far as I know from literature searching) who has been looking into it from a long time. Here is a very recent review by Sathiapalan. The introduction and conclusions of it look very nicely written.
Can someone discuss in detail where actually does the problem of background independence occur in string theory and the progress so far in this direction.
