Hi Petr. I (as the author of fgms) would be pretty much interrested to implement fgms as part of a HLA infrastructur. What detained me from going that way is, that I found no free (as is free beer) documentation on HLA specifications and the quite complex structure (too complex for a one-man-show). Additionaly I'm not sure about license issues involed. Are we allowed to publish all parts of (our) HLA infrastructur under the GPL (which will kind of undermine cash-flow of documentation providers like the IEEE)?
