This idea was mentioned by Peter in an earlier thread. "Best remote app for iPad".
In that thread Peter suggested an Apple Airport Extreme WiFi interim router might work. Since wifi is "not allowed" on the machine running XXHighEnd.
This solution seems to be working well for me and I prefer it to the solution using an interim PC and blu-tooth dongles.
If you connect an Airport extreme to your ethernet network and the machine running XXHighEnd to the same ethernet network, your wifi devices connect to the wifi network provided by that airport extreme. The wifi devices and your XXHighEnd machine are all using the Airport Extreme as their router and their IP addresses are all served up by the Airport Extreme.
Now your iPad can talk to your XXHighEnd machine, because they are on the same network. WiFi is disabled on the XXHighEnd machine, so can't pollute it.
On the iPad I've currently experimented with PocketCloud and Splashtop.
So far I'm liking Splashtop better. PocketCloud can connect via RDC. With all bells and whistles of XXHighEnd activated, including Phase Alignment and MinOS, PocketCloud can remain connected when the music starts to play in unattended mode. This is not good, because in my case I heard some pops and ticks along with reduced SQ. This I think is the objection to having the LAN switched on. Note though, that I was also pulling the music from a NAS Drive connected to this LAN.
Splashtop relies on a server app (Splashtop Streamer) running on your XXHighEnd machine.
When you start the music in unattended mode using the Splashtop client on your iPad, Splashtop complains that the network connection is "weak" and it can't keep it up. Poor Splashtop
This is good though, because XXHighEnd continues to play the music you selected on your iPad, sans ticks and pops, with great SQ.
Hopefully you will be able to reconnect, once your selected music has stopped playing. I'm waiting until I get to the end of the Madredeus album I'm currently enjoying.
Hope this helps anyone who's looking for a similar solution and has an external wifi/ethernet router like the Airport Extreme.
