Does ios remote control app need to be on the same network to control the tv?

I was just wondering if I could use the Tivo app to control my television if I was not on the same wireless network (i.e. not in the house where the Tivo is). I don't have a Tivo yet, but am considering the purchase. My Verizon FIOS ios app must be on the same wireless network as my tv for it to control the tv and I was wondering if Tivo was the same or can control it from away from the house.



I want to do this so I can use my Slingbox on my tv in my vacation condo, but control the tv at home using the Tivo app so I don't need to scroll through the screens to find what I want on my dvr. I could use the Tivo remote to pick the show I want by scrolling through the list on my iphone and then hit play and the slingbox will put it on my tv.



Will this work? My understanding is that the Tivo streaming software won't allow me to watch on another tv so I'll still need my Slingbox to show it on my second tv.



Thanks.
