It was demonstrated last year during the Chicago MAX 2007 to run Quake. A few months later it has been demonstrated to run a Python interpreter and Nintendo Emulaor. One interesting tidbit is that the thing is built upon the open source LLVM Compiler Infrastructure.
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
