I am not particularly interested in its portability or compressibility aspects, but the fact that slim binaries preserve the control flow structure of the original program, this enables (among other things) interesting solutions for aggressive (re-)optimization based on run-time profiling data.
I also like its security aspects (like not being able to construct slim binaries that violate the scoping rules).

I don‘t have access to OMI / SlimBinary source.
On the other side, I wonder whether this concept is really needed anymore. Seeing that the RISC-5 CPU is running emulated on Windows, Mac and different FPGAs one could say the RISC-5 „assembler code“ can be seen as kind of SlimBinary :-)

Like the Java classes can run in any JVM. The goal of SlimBinary to distribute executables that can run anywhere  is somewhat reached, isn‘t it?
