Sorry, I don't get what you're trying to say...
Maybe you should clarify what you're asking.

Abyways. Just a poll : What sort compression (Win32-API/Arithmetic/Huffman/whatever) are you using in your demos/intros?! I'm interested...
I wrote an adaptive huffman coder with BWT/MTF2/ZLE in < 1kB Code. Is that good or are there ways to get decent compression with less code?

If you're targeting Win32, you can always use expand/extract/extrac32, which has come bundled with every Win OS since '95. That includes LZH and Quantum compression, which are both pretty good. Then your unpacker overhead becomes ridiculously small. There are tools to do this, or you could roll your own. (Hint - there are quite a few methods which can drop the compressor overhead _lower_ than 20to4 - check out the CAB file specification for starters).
