Checking regularly isn't that big a deal- even if, for example, it was
only done on a map change or death or in "suspicious" cases (20 frags
from one player in a row). The checksum is a very small value (only a
few hundred bytes at most) and could easily be slipped in. Since it's
so small the server could easily track the progress of characters - when
a character is "alone" (far away from others) then the request for the
check could be made.
The problem here is that Valve wants the best of both worlds and I doubt
they'll get it: they want the most advanced and easy to use modification
engine ever AND the ability to stop cheaters. I doubt that you can open
up the guts of your app as much as they want to and stop all cheating.
It'll be interesting to see them try. but I'm really skeptical.
At the very least somebody will determine how to spoof the checksum or
even lower, the checking software.

But they'd have to check regularly, since it could be possible to have
the Steam server validate your software's checksum or something and then
load a 'helper' to facilitate those 100% headshots.
