Also, if possible, provide both a local and remote query tool. You could go like this:
TaskListTasks()
TaskScheduleTask()
TaskRemoveTask()
TaskAddTask()

I would not use the abbreviation TS as this might get confused with Terminal Server.

You might also want to copy the UDF header style that I and some others are using. See e.g. the DBCommand() UDF.
