Different hardware bound to one worker in pool

[yankijra]

Hi,

please advise:

0. is there any difference in productivity if you bind different hardware units to different workers or all to one mining for a pool?

1. what variable difficulty will the pool assign you in the latter case? will it be variable per connection (every hardware unit will have its own connection with same worker name) or per worker?

2. will the pool give enough non-overlapping work to all the connections of the same worker name?

P. S. I know about mining_proxy (don't want to use it) and monitoring every piece of hardware binding them to different workers (they are already monitored the other way).
