The only flaw was that I kept having to dive across the sitting room to start Babytype whenever Johnny approached the keyboard, which he can now just reach. So I asked Raize software if it could be turned into a screensaver, and got the following helpful answer:
First, you need to go to the directory where you installed BabyType. The default location is "C:\Program Files\Raize\BabyType." In this directory, you will find several files. One of the files is named "BabyType.exe".
Select the BabyType.exe and then select the Edit|Copy menu item. The select the Edit|Paste menu item. This will create a copy of the file which will be named: "Copy of BabyType.exe".
Next, select the File|Rename menu item and change the name to: BabyType.scr
Then finally, select the File|Install menu item and Windows will install the program as a screen saver.
I would like to say that this works perfectly, that the sitting room PC is now goes into Babytype after 5 minutes without use, and that the reply was sent on Saturday night, which is pretty damn impressive for a product that currently costs a mere $19.
Great product, great attitude. Thanks!
