Yes, we'll be incorporating more coins over time. Adding coins to CoinRecycler isn't difficult; it can support any number of different coins, the infrastructure is in place, etc. But, each coin's wallet still has to be compiled, the blockchain must be synced, it has to be kept up to date.. so there's certainly some level of overhead to adding new coins.

Are there specific coins you're interested in seeing added first?

Our main development effort at the moment is to get the GUI wallet integration completed, so we've put off adding more coins to CoinRecycler for now. We may add some in the next day or two if time permits though.
