BE DeDup and OST Target on same server

Given that there are limits/restrictions for the BE Dedup, is it the same for OST compatible appliances.

I am looking to purchase some StoreOnce applicances and backing up to NAS targets.

My question: Will we be able to address the StoreOnce NAS targets and a BEDeDup folder hosted from the same server?

Are there any limitations to the number of NAS targets or the size of the NAS targets?

Are there any additional licensing implications?

Thx,
