Thanks to Strikermax, something key almost passed me by.
Presently, it isn’t know how easily a client can be made, but with 3 developers behind ZHC0 answers will soon be forthcoming. We can always cast our cause towards the bitcoin forums at http://bitcointalk.org if we are desperate.
We can safely assume that a mobile client is just a matter of time. If a mobile client isn’t possible, it might be the key transition point between ZHC0 and ZHC1.
