Having said that, it looks like the HTTP server is the USP here. Being able to have non-techies run Fabric tasks is definitely a goal that's passed me fleetingly in the night. So, add this to Fabric and we're good.
EDIT: The author, Dan Lecocq is near me in Seattle so, what with it being a small world and all, I just wrote to him (in case he's not the author of this thread) via his blog to ask him what he didn't like about Fabric, and suggested he respond here.
