Here are some screenshots of the "gpumon upgrade" that is to be included in 0.5, if we ever do decide how to release that thing.
In a nutshell, it adds basically all the extra stuff that cgminer does to phoenix (all completely optional of course).
Auto fan and GPU clock management, flexible pool failover (multiple strategies and whatnot), lots more stats to stare at, tons of settings to tweak, yadda yadda.
Lock up your machine with style... like never before.
And if that wasn't enough...
but wait, there's more...
The new autoconf tool is sort of like DHCP for entire mining configurations. At boot the client gathers details about the GPUs it detects and listens on the network for an autoconf server. If it hears one announce it self (or overhears another client talking to it), it will then submit the GPU details it had collected and ask the server for a configuration.
Provided the server knows enough about those GPU models to provide one, or at least has a minimal set of defaults in place, the new rig begins mining for you without ever needing to be touched by hand. Further refinements to it's configuration can be done from a central web based console.

Change pools farmwide in seconds, just takes a couple clicks
Issue commands and gather responses from groups of miners in one operation (run fixer, reboot, etc)
Add much, much more in this limited time offer.
So.. lets sort this whole 32 bit vs 64 bit thing out so I can release a 0.5 image and get this party started, eh?
