I got a .net service which runs powershell scripts

All,
The Xymon powershell client is coming along, but I've run into some annoying issues which are little to do with powershell itself and was seeking some advice if anyone is more familiar with options available for Windows for running services and 32/64 bit environments.
I was just testing on a 64-bit 2008 server, installed service from an interactive shell, created a reg key with servers list I want to use then started service. Problem was, it didn't find the reg keys. Turned out that XYMONPSCLIENT.EXE (ABC-SRVANY.EXE) is running in 32-bit mode, and despite the PDF doc suggesting it can run 64-bit apps, and that the explicit path for powershell.exe appears to be the 64-bit version, it started as 32-bit and couldn't find the reg key because it could only see HKLM:\SOFTWARE as the HKLM:\SOFTWARE\WOW6432NODE subtree.
I could put in logic to detect that and explicitly use WOW6432NODE even in 64-bit mode, but there's no reason to be running in 32-bit mode when it should be possible to run 64-bit when running as a service. I also have an issue with ABC-SRVANY.EXE, that if the child powershell process dies for whatever reason, the service process is still running but it doesn't seem to care, doesn't try to restart, doesn't exit (which would allow Windows service restart options to take effect), just sits there!
Does anyone have any suggestions? If someone is able to write a basic (.Net-based?) .EXE service runner that just calls a powershell script and runs in 64-bit mode if it can, 32-bit otherwise that would seem ideal. All it would need to do is start the child process, handle service stop/start signals and manage the child process, and exit if the child dies. Doesn't sound hard, but I have no development environment for that available so don't really know where to start.
Thanks, David.
