chrysx, i have been running .conf files for ages now under kopiemtu.  I can switch algos like lightning over ssh and can also start and stop mining very quickly with a single command:

mine "stop", "start", and "status"

the .conf files are stored in a known directory. issuing the mine "switch" command cycles through all the conf files in the directory and writes to a miner.conf file which ccminer will read from the next time it's launched with mine "start".

it's very convenient and the reason i've stuck with kopiemtu, even with the broken stats and monitor program.

it would be nice to have all the switches available in ccminer spelled out for usage in JSON-RPC format, instead of the single letter abbreviations in command line mode. (i.e. "algo" instead of "-a")
