" avg price is not multi-company ready "

Is OpenERP accounting itself is?
This is another related bug, but not in this bugs's scope.

"current avg price can not be used to compute historical stock values (but is currently done in OpenERP)"
Agree it can not be used. Therefore you added nice fields in stock.move object "move_value_cost" and "move_value_sale"
For those purposes.

"I even would assume it's against the law in Austria to use an higher current avg price for stock evaluation at time of refund"

Maybe. I do not insist that my proposal is right. What I wanted to say that AVG price itself should not be recalculated on any refunds.
