This can be overcome in most BT clients by pre-allocating the space for
the download at the beginning.

Not a problem, each piece is hashed and checked. Anyone feeding you more
than a few bad chunks (accidents do happen) gets banned (and you accept
no more from them). Only possibility I can see for foul play is if the
original seed was a trojan. And that can be checked for with public
md5sums, which already exist. (Ie: Downloading things from suprnova.org
is potentially hazardous, especially to Windows systems.)
