I like your setup Skip...! I was thinking of having a "mostly" Plan 9 distributed solution, with an Inferno registry node in the mix (per Pete Elmores debu.gs tutorials and 9gridchan tutorials). I may end up doing the GUI on Inferno too, as it has quite a few more primitives that'll make it look "friendly." I'll have to read Philips book on Limbo programming for that.
I was thinking of having the Mac9P/ 9mount on Linux there in case I needed it, but yes, you're right about authentication and the like.
