is probably preferable -- higher (although still modest) data rate and
two-way communications.

I guess no video at that rate - or even audio.

Not at those rates, no. Ample for bringing back individual images if you don't go hog-wild on the megapixels (there are reasons why cameras on deep-space missions, in particular, tend to top out at a measly one megapixel), adequate for trickling back an occasional short compressed video clip, and fine for many types of instrument data, but you won't get real-time video. And you may not want to, not when you're paying by the byte -- 30MB/day sounds good, as does $0.00002/byte, but when you multiply those together, that's $600/day!
