This is exactly what I do. Difficulty varies from completely trivial to 
impossible depending on how comfortable with computers you are :-)

Hardware and installation requirements:

1. CAT interface for your Icom. I use a Rigtalk.
2. Computer near your Icom. Any 1GHz Windows machine will do. The computer must 
be attached to your home LAN, of course. Put it on a fixed IP address so it 
never changes. For most home wireless routers this means give it an address in 
the .10 to .99 range.
3. Computer-sound interface for your Icom. I use a Signalink USB but for just 
listening you can get as low-tech as putting the PC microphone next to the Icom 

The number of commercial products and homebrew plans for hardware interfacing 
can be bewildering. If this is true for you I recommend starting very simple, 
i.e. Rigtalk and PC microphone (receive only) and then building from there.

Control software and installation requirements:

1. Open the HRD documentation on your laptop and keep it handy. Follow the 
excellent directions therein for each step. 5 minutes.
2. Install HRD on the PC next to the Icom. Get it running locally with the CAT 
interface and radio. Should take all of 5 minutes. Use CAT PTT.
3. Within HRD install the HRD server service on the PC. Another 5 or 10 minutes.
4. Install HRD on your laptop. Configure it to attach to your HRD server on the 
radio PC. Again use CAT PTT. 5 more minutes.

Once step 4 is done you are thinking "Man, this is really cool!" and can't wait 
to remote the sound. This is a bit more difficult because the documentation and 
stability of the sound software is not as good as HRD.

5. Install either IPSound (http://xoomer.virgilio.it/ham-radio-manuals/) or 
Skype on both computers and get it running in both places. I used IPSound 
because it is very lightweight but it is very poorly documented. Get sound 
moving between the PCs.

You may have to do a little trial and error hacking here, especially with sound 
levels. That is the nice thing about something like a Signalink or a 
Rigblaster: just put all the PC volume controls at max. then set the level with 
the interface once at the radio and be done with it. I put IPSound in the 
startup folder on the radio "server" for convenience.

6. Start enjoying listening. Since the sound is moving to/from your laptop just 
install any digital mode software on the laptop and use it there.

Once you get that far report back and we can chat about other subtleties such 
as calibration in a remotely operated setup.

Keep us posted on your progress. With the radios you have I bet you have 
everything you need in your shack already :-)
