Taking a quick look at deltup-0.4 (most recent available via 
sourceforge), it is still reliant on having an older version of bzip2 
installed to handle cases where the target distfile was compressed w/ 
the older version of bzip2.  That strikes me as side stepping the 
problem- say down the line, either the bzip2 or gzip implementation was 
tweaked again to produce a slightly better compression, you'd run into 
the same problem again of maintaining md5 correctness.
As I had mentioned in the past on this ml, I'd think some solution 
allowing for an md5 checksum of the data rather then the compressed 
form of said data would be a better solution.  On the plus side, it 
could be extended to allow the user better control over what 
compression is used on their distfiles, but that's ancillary to the 
problem I mentioned above.

Other then that point of contention, kudos on bdelta's performance.
