Looks a bit like my Fexl (http://fexl.com/code), though Fexl has a much smaller grammar and footprint. I'm not sure I have all the "capability" and "distributed" stuff though, and I definitely don't have threads, much preferring "fork" (i.e., O.S. level blocking system calls with timeouts are my friends).
This name collision is even worse than you suggest. Lindenmayer systems (L-systems) were invented back in the 60s and have been called L-systems for years.
(Incidentally, GA Tech is my alma mater.)
