Genesis on AmigaOS 3.9 may be unlicensed but unlike Miami in 3.5 it is not as crippled as that. As far as I know its practically the full version. I have used it and never came across any thing that was 'crippled' in it.
I do recommmend getting OS 3.9 as its still available unlike other TCP stacks (Termite TCP was done by HiSoft which is no more...).
