Sounds like a trick question, but Netscape's latest beta from September includes scripting support. Rumor has it that they're going to rename it to JavaScript later this year since Sun is pushing for strategic alignment with their Java platform. (You can use it to script e.g. applets). But you can embed the decompression code directly in the file, writing it in the scripting language itself—no compiled bytecode (or even a Java plugin) is necessary.
