I'm afraid the situation hasn't changed...

For the time being, you could pretend to be the Workrave toolbar and send 
WM_USER messages to Workrave. I attached an quick&dirty c# program that 
illustrates how this can be done.

Note: This is fully unsupported and is very likely to break in the future (It 
depends on magic values that I do not control).

Groetjes,
