I'm actually trying to avoid slicing on the same machine, as i usually do it in concert with tweaks in CAD, fixes in Netfabb etc. So controlling the machine locally is the only thing, with the ability to upload an already sliced gcode model to SD card on the machine.
The idea is to use the (remote) web interface for control whenever possible, and in that scenario, there are no benefits from slicing on the server - i'm sitting at a far more powerful machine anyways. However, if i'm setting up a print manually and/or debugging, a local screen is a must. I normally use a G-code console for that, but with a touch screen that's obviously not very convenient, so a pronterface-like panel is what i'm aiming at in that scenario. Something like VizPrint's UI, perhaps, but with multiple extruder and SD support (and less crappy):
For everything else, there's the remote web interface.
PS: LOVE the future plans for the API and modules! In that name, i've contributed a small donation via the site :)
