The last time I was working on it, it was pretty much functional, with most errors / inconsistencies related to svg defs which were not shared properly.
I havent had a change to compile in a while, but ill run a quick test today and get back to you about any connections problems.
I havent been around or had the time to work on Inkboard for a while. but I should be able to get back into it within the next few weeks
(Promises to have 0.46 release worthy inkboard)
