Is this possible? I remember back in the day using a diplexer to combine and then split again the dish and OTA signals through one line. Can the same be done for Comcast cable and Dish?

This might help the OP: I ran into this situation this weekend. I've got Dish and now cable internet as well. I wanted to have my router in the basement w/ the HT gear (ps3 and computer mainly) so I could have them hard wired. I figured it would be simple enough to take the current coax for sat, tape another one to the attic entry point, pull it through and have two, one for each. I got in the attic and saw where the cable went down, and knowing where it came out, figured it would be impossible to run a second one. But I tried anyway and the cable wouldn't even budge in the wall. Dang....
So I'm getting cleaned up and I figure, why not see if I can run satellite and internet thru the same cable, and just split it once it gets in the basement closet? I didn't figure it would work but it was at least worth a try. So the dish comes in and gets split, one to the basement receiver and another to the spare bedroom (Dish 722 feeds both from the basement in case you're wondering). I took the feed for the basement, and using a standard splitter, put the cable internet and dish, in the two out portions of the splitter, and hooked the current coax to the basement into the in side of the splitter. I then went to the basement and split that cable into two separate feeds, one to the dish receiver and one to the modem. It all works beautifully! I was able to record three shows and watch two different shows (from DVR) all while doing speed tests and maintaining my full 15mb service!
I realize that I should have to use a diplexer instead of a splitter on both ends of this, but I didn't. I used a simple RCA brand 3-way splitter. I've tried finding a reason for this on other forums but haven't gotten a definitive answer. Any thoughts?
