Yes player docking can be done, they managed it on Hamburg City server and the dev team have been playing around with it for the next freeworld release but it is very buggy.
Also to ad to what Yuri Neova said about the freeworld kami (ships/missiles), this actually got expanded on in freeworlds version 1.66, you could buy wing men at the base, there would be 4 figters flying in formation with you everywhere you went and when anyone hostile to you came on your scanners they would engage, thay would stay with you untill they got destroyed, pretty cool.
