miaviator,

I'm running 2 RPI's with the LRP and haven't had any issues.  Just run it from a Linux or Windows box on your LAN (I know you have some dedicated machines around) or even run it as a Service if you don't like having the CMD box open/minimized.  I know you're asking for an installer so you can run it entirely on an RPI, but saying that users with RPI's cant use LRP is slightly innacurate.

FYI, I run mine with the API listening ports enabled so I get accurate hashrates and everything is peachy.  You might need to poke some holes in your local firewall to make things work, but once you point your RPIs at the machine running LRP it makes things actually easier to manage pools and such (especially if you're running more than 1 RPI)

Msg me if you want specifics on my configuration settings.
