Error Correction...

I mentioned this before, but I don't think anyone responded (so either it got 
lost in the mix or was a stupid idea).  I think that the each block should be 
cryptographically signed - because otherwise it will be impossible to validate 
the signature (at the end of the archive) without reading the entire archive, 
this would also provide error checking.  You don't want to restore any file to 
disk until you've checked the signature, so by signing on the block level you 
permit operation on a stream (a block at a time like gzip and bzip2 do).  
Admittedly this will add a few bytes to each block.
