RF remote. Then use the spiders (unless you have fancier connections, which you probably don't, unless you bought pretty fancy gear).
For instance, this will do the trick, and it's only $85 shipped for both native IR/RF, WITH the base station.

IMO, way more reliable than Harmony, and way less of a hassle to program.
you can spend more for sure, but this is the best value. this remote can't discretely control TWO DIFFERENT av systems at the same time (w/o affecting the other system for instance).
otherwise, the sky is the limit for automation. having a pro program something like crestron, rti, whatever, costs a whole lot, but you get reliable performance that even grandma can easily control.
for your cabinet, there are two main issues. 1. Heat dissipation. 2. size enough for components. choose wisely. personally, I don't like the idea of electronics up front. how about a closet? 35ft hdmi is mebbe $50, and that remote I linked is $85. That's only $135 to be able to put the components anywhere else in the room.
otherwise, some av stand links

otherwise, I say save the thousands of dollars, have it all even neater, with both better video and audio performance. well not video in your case, but audio potential increase is pretty great w/o the cabinet up front. possibly of epic proportions in fact, but whatever.
Hi everyone I'm new to the forum and I was hoping some one could help me out.
My parents are looking to upgrade their home theater set up. My mom would really like to have all of our A/V components in a closed up cabinet (with out glass) underneath our TV. I told her that we couldn't do that unless we reconfigured everything with RF stuff. However, we went to a high end furniture store earlier today and the Interior designer we talked with showed us that some of their entertainment centers came with this thing called a SmartEye that she told me uses the IR receiver in the TV to control all of the components tucked away below. I had never seen something like that but thought it was a great idea. So, when I got home I tried to find out more information online but unfortunately I really wasn't able to find anything.
All I was able to find was a .pdf from the furniture maker that includes the SmartEye:

And a British website of the manufacturer, but what is up there is not the same from the .pdf:

I could not find anything about ordering the product in the U.S or anything similar. I was just wondering if anyone else had ever heard of this or something similar and how well it works.
Thanks for the help
