If security is the problem, you could configure the HTTP part to
listen only on a loopback interface. (yes, this is supported on NT and
windows 95 too)

I always thought the use of Client was very elegent. The performance
hit is negligible, and all the plausible alternatives need many more
lines of code.

Another advantage is that it promotes testability of the scheduled
events since it is easy (trivial) to reproduce the environment in
which they run when scheduled.
