We also will need to decide if we should prioritize getting an Android wallet up and running first. I know Ahmed is willing to do this for 1 BTC.
https://coinomi.com/Maybe ask the developers for inclusion of TRC? I've tinkered with it a bit for a few coins and seems reliable (so far, but we all know how that can end)
I say hold off on mobile wallet until after adding anonymous transactions so you wont have to pay to update later.
as far as which anon tech is better not really sure would have to research each one in depth.
@clock maybe you start a separate thread asking the community to share their thoughts on the current available anon technologies.
On another note; TRC volume is way way up 17+ BTC
