Why would TCP have trouble with asymmetric links? And if you
mean links that only allow traffic to pass in one direction
(there is no alternative backchannel), you really can't have
reliability.
For end-points that change IP, either look at SCTP, or build
a protocol that allows you to establish new TCP connections and
switch the logical connection to another TCP connection.
There are _really_ good reasons for using TCP, and really quite
few for not using it. In most real world scenarios, you end up
reimplementing TCP bit-by-bit, in your own protocol, over UDP.
Also, apt-cache show rocks.
