Unfortunately this won't work. BZ2 compression is based on 'redundancy' in a 
message. There is hardly any redundancy in short messages as used in k-to-k.

The only way you can do that is by using context-based compression, like the 
'context based huffman' compression in pskmail, which reaches compression 
factors of 1 ... 50 : 1.
