Not anymore. In fact, not for a number of years now. Part of the reason -- I
can tell you, having been part of both the problem and the solution -- is
that offboard processors never were more than a stopgap.

I think you're vastly overimpressed with what even the best current QSK
radios are actually doing, and that you're vastly underimpressed with what
current off-the-shelf hardware and software are actually doing in practice
all the time these days.

In any case, the idea that a rogue service routine can sneak in behind you
and corrupt your timing is, on a properly configured system, just silly.
