With this being so small, maybe we could use it as an alternative to perl2exe? Throw in the recent .par distribution method and we may finally be able to distribute perl applications...
PodMaster and I are working on that, and TinyPerl use the same idea, well, it was the first to use this. TinyPerl has a small script inside it that loads LibZip before run your file.
About UPX I don't see any difference in the performance, they made a very good algorithm for binary compression, and it's very fast!
