I've tried it on some of my julia code. The lack of support for dynamic dispatch severely limits the use of existing libraries. I spent a couple days pruning out dependencies that caused problems, before hitting some that I decided would be more effort to re-implement than I wanted to spend.

So for now we will continue rewriting code that needs to run on small systems rather than deploy the entire julia environment, but I am excited about the progress that has been made in creating standalone executables, and can't wait to see what the next release holds.
