I know someone who makes kefir from coconut milk...well I say it's kefir, but really she dumps a packet of store-bought cultures in coconut milk to get a reasonable facsimile of kefir. She also sometimes uses fresh coconuts, ferments in the shell, and then scrapes the fermented meat out and uses it something like a cheese. I never tasted this "cheese," and have no idea if it's any good or not. One thing I noticed though, is the coconut culture gave off a VERY strong eggy/sulphuric smell that's not terribly pleasant. This could have been unique to the cultures she was using and not the fact that it was made with coconut...not sure though.
Anyway, I'm pretty sure all these things will ferment with a kefir mother culture, and I'm not saying your kefir is necessarily going to poop out after some time without milk, but it has been suggested as a possibility by others (sorry I couldn't give you the reference here.) I have heard of others using something called a "water kefir" mother that is apparently more adapted to vegan ferments, but I don't really know anything about it or where to source it.
