1) FSP has mainly been used for 'underground' purposes, i.e. GIFs, pirated
software, and so on. (That may have changed). Many sites disallow it on
this basis.
2) The major design issue of FSP, namely that it uses UDP instead of TCP, is
flawed. UDP doesn't have any of the congestion control or avoidance
systems that have been placed into TCP over the years. FTP is just fine
on modern IP systems, since network transients don't tear down a TCP
connection anymore (That was a BSD bug, and has slowly been eradicated).
Apparently, FSP has started causing problems already on some slower IP
links, since it doesn't do any congestion control. It's only a matter of
time before the larger network providers notice it, and take steps.
>From a security point of view, it's like any other UDP service, i.e.
impossible to control. :-)
