I suggest not using light grey type in the URL input field.

Also, could it sense what country the requester is from and use English if from the US?

I tried this on three sites:

1) http://www.bostonreview.net/BR37.4/oded_naaman_israeli_defen... -- looked perfect

2) http://www.freakangels.com/ -- formatting error at bottom text

3) http://mikecanex.wordpress.com/ -- it substituted the typeface

I think there might already be other services like this out there.
