Thanks for bringing this up. We discussed the need for additional symbols
at the meetup, and it may very well be that we do come up with a custom
font with a selection from font-awesome plus additional symbols designed as
we go along. Very good idea.

Thanks for the pointer. I mentioned grunt in particular because it's quite
mature at this point, was the default tool for the yoeman project builder I
used and is also the tool of choice for Storyboard. If there is a
compelling reason to switch though, I imagine the Storyboard folk may also
be interested. From a brief look around there does seem to be a lot of
enthusiasm for gulp. I will look at making a branch of angboard that uses
gulp to get a good feeling for it (unless someone produces a PR that does
it for me ;)
