Requesting data from an http/ftp/nntp server is a bit different from
opening up your filesystem to people all over the world, hoping the
program doesn't have a buffer overflow or a back door that gives
someone full access (assuming it was configured securely in the first

It's not a predicament at all; I happen to agree with the policy :).
In the present case of MacTeX, it not necessary to use p2p, so there's
no justification for it. I do agree that being informed is helpful,
and Wikipedia's page on file sharing has a risks section  that
links to a recent paper  on the topic. As far as I'm concerned,
the bottom line is that the risk to personal or other sensitive
information on your system should be carefully weighed before
installing p2p software.
