Re:
Any other comments or suggestions are more than welcome.

GingaDin,
If an application from another user has reached a point where, let's say it's at point "B"
Point "B" is where selections are now presented in whatever format your application requires at *your* point "B", being let's say, the software you have described to send the bets to various TAB's.

How,where and I I or anyone else "arrives" to point "B" may not be a concern to some as much as it is to others.
How then does each and everyone's different methods/systems interface on common ground ?

For others who may not yet have an understanding, I hope you don't mind if I show this in a graphical form at the absolute basic pencil to paper stage
(before code phase).

Just something I do when it's "time out" during brainstorm.
