yeah i will say that issues like you just described with maxconn inbound etc will work exactly like bitcoin with v.9.x i have working now. I know because the code .9 started as a github fork of bitcoin and I haven't changed anything to do with the connection scheme or logic.

I think it's safe to say that the behavior you described was added after bitcoin .5 or .6, wherever sexcoin was forked from. Sexcoin was never updated with really any features from bitcoin after the fork.... as far as I can tell.

That is one major goal with sexcoin-ng, it is a true "github fork" that you can easily compare and create pull requests via web interface.
We can rebase/merge and keep in sync with bitcoin or at least only slightly behind it.

I'm waiting to rebase what I have now in https://github.com/sxcer/sexcoin-ng until i finish a sexcoin-ng-qt branch(where i'm modding the qt client) and get it merged into master.
