I was going down this TCP route today but just realized something. Isn't the Windows Firewall going to ask to block or unblock the selected port when the TCP server starts? That's going to be a bugger and not user friendly at all.

Since Vista came out I've been using a small program I wrote with a manifest to give it elevated privileges, so I can write to the HKLM registry when requested by any of my applications. I use a shared memory component (memory mapped file with no file) to communicate between an app and the small program which is loaded when required. But since Vista SP1 or SP2, Microsoft appears to be preventing shared memory access between an app with standard privileges and one with elevated. I've been wondering why some users have been reporting odd problems and this appears to be it. So it appears I need an alternative method. I could use the elevated DLL method, but this seems complicated. I'm not an advanced programmer. It's a bugger as I spent quite a bit of time getting this working well when Vista first came out. I would prefer to continue using the small app, but it appears I need some other method for sharing text between 2 processes of different elevations. Does anyone know if this is possible? I've heard that even PostMessage and SendMessage from a standard to elevated program does not work anymore.
