i have read a reply from them stating that sHive can't be done

Ok... It may be because "yield" on HP is based on active curation. So they can't guarantee yield without messing with curation, and they probably don't want to mess with that.

we will just have sHBD... i hope it won't be too complicated for not expert users

It may be. As I said in another reply, that's why more people keep money in the bank for interest, rather than trading bonds on secondary markets.
