Is there a ZcCoin wallet for linux?

Multipool is an easy way to collect a variety of coins without the hassle of setting up accounts and switching pools.  Also if you are new to mining, it will introduce you to the different coins out there and you can learn more them as you mine. 

dump, the block reward is too damn high

There is no train Neo

Good call, perhaps for that specification it is best to use 2 instances of cgminer.  However who is to say that they will not be doing the same work?  I have not done such a thing but you have sparked my interest and I may attempt it.  Perhaps I could mine multiple coins with one rig?

Antigravity and time travel will be very profitable

By 2020, people will not be thinking of BTC in terms of value based on dollars/euros/etc.  It will most likely evolve into something new completely, or perhaps just an upgraded version.  The blockchain by then would be enormous.  Bitcoin is revolutionary but not perfect.

The math involved with Primecoin's proof-of-work is fascinating, as there is no other coin like it.

I'm here for the community around the scrypt & cpu alt-cryptos, don't have much interest in Bitcoin or the other SHA-based coins.

If you plan on mining the same coin with both cards I would recommend to use 1 instance of cgminer configured with 1 worker.  You can specify settings for each card in the config file, for example "thread-concurrency" : "8196,22400".  If you are unsure which card is which, you can start cgminer with the flag -n to list all the cards.
