Roland and I wrote an app called
iWitness. Maybe you
heard about it.
The
wiki page over at the OC gives a good description and has decent instructions. You can also download the latest version there.
This Party Poker script opens, and keeps open, tables with your defined characteristics. For instance, you want to observe $10/$20 and $15/$30 6max Limit Hold'Em tables with at least four players sitting. iWitness opens that type of table and watches to ensure they maintain enough players. If the table starts to empty, iWitness closes it and opens a new one.
This has nothing (directly) to do with .hhf files. You need a handgrabber like Juk's
FPHG to write those.
Any questions, feel free to ask them here.
