It's great to see work like this being done. Thank you for releasing 
your work to the community. However, I wonder how well this release will 
be supported. Is there a development team, someone responsible for 
maintenance and bugfixes, updating it for recent OS/tools, a roadmap for 
the future? Getting a simulator out the door is extremely important, but 
it's also critical what happens to it after it is released. If there is 
no community around it, then it will just be abandoned. I have heard 
good things about SSFNet, for example, but the latest release was Jan 
2004 and as far as I can tell there is no-one continuing this work. I 
hope that I am just mis-informed. Rightly or not, this severely 
discourages me from using the simulator. This is the one thing that ns2 
has going for it: it's still actively maintained and probably will be in 
the future too. Whether or not this is a good thing is left as an 
exercise to the reader...

This is, of course, an extremely difficult issue to solve. Can we make 
it part of the networking research community program to build and 
maintain a good toolkit for doing research?
