Since Compress only uses printable ASCII characters, hopefully if you paste the above string into a notebook and perform:
Of course, it is also possible to paste the raw output from NotebookGet, but that will be considerably more voluminous. Also a compressed string that becomes corrupted will be utterly destroyed, so it is probably safer than using the raw BoxForm expression.
NB: The 9.0 bug that messes up cell merges, also affects NotebookGet, so I would suggest you use 8.0.4 for this trick until 9.1 comes out.
This is really a test to discover if this survives the posting process!
