Chat-server processes now on ground-vm, no at-meta-level necessary

Hey Tony. Going over your chat example. I don't understand why you need to spawn a new vm in the server. Also it seems to me that your (at-meta-level ..) are nested too deep, so it looks like they should've brought you below the ground-vm so to speak. Either I don't precisely understand how (at-meta-level ..) work, or there's a lower level safe-guard that leaves you at ground-vm once you get to it. Its as if u had too many closing parens, which interpreter just ignore.

Anyway, bringing everything onto the ground-vm and therefore removing all (at-meta-level ..) wrappers still leave us with a working app. Have a look at the diff. What am I missing about your implementation?
