Again I'm really not trying to get into a sales model. I'm just thinking that
if it's useful enough to someone to sell it, then the authors should get
a nominal cut of the pie.

May work. I'll need to think about it some more.

If I find a few minutes this week I'll post the current specifications and
some code examples. If I can find it I'll post my burglar alarm system which
is the biggest piece of useful code I've written so far.
