Am I correct that there is currently no way to change from port 8333 and that this will possibly never be a feature ?
Technically, no. You can change the default port now and it would theoretically work, just very, very poorly.
But yea, it will probably never be added due to various security/networking concerns about the results of it. I agree, its a cool idea to add in theory, but there are too many concerns about it and in financial software, thats just unacceptable.
