Bob -
None that we know of. Also, the effects of LZW encoding might be lost on
parcels as small as simple strings. JJ and Carl are more up on LZW than I, but
I believe it analyzes a larger cross section for redundancies, and then builds
a table based upon the frequency of the redundancies.
If you were only working with ASCII, you could write your own that would take
characters and mash them to 7 bits. This way, you could have 8 characters in
every 7 bytes. If you were working with non numeric, or all upper/lowercase,
you could probably get a better compression as well by using less bits (6 or
5).
