Thanks all for interested.
A long time i'm not update for NS2, because I need time for work (life that) so I do not have much time for NS2.
It takes more time than I estimated and I can made only in my free time, however work is continuing.
Release date possible in late August or later ( I hope can be completed on my birthday 05-08 )
Release method could be with support forum and two version:
+ Classic: Basic functions, free download and support via forum.
+ Premium: Advanced functions, paid download, custom as request, support via email/skype/forum...
P/s: Will certainly not make you disappoint
