I'll double check, but yes, (at least for the version you posted yesterday...I hadn't updated to the one you just posted yet).
I tried outputting directly to a building. I had two item busses, one with two filters, one with one. The bus with one filter worked, the other one didn't. Oddly enough, even when I set it to one filter it still didn't work. I had to revert back to my intermediate chest trick.
As far as fluids go, I need to play more with this. When I loaded your latest version (as of last night), my fluid "transfer" networks needed me to pull up all of my pipes and replace them to get them working again...So, there's lots of little oddities that happen...I can pay more more attention to them, and give you save snapshots with the problem right when I notice them, if you want...
