Not sure if this has been asked and answered already, if it has I apologize.
Will the current (non stratum) interface be removed at some point? I've been mining for a little over a year at BTC Guild with a non standard FPGA setup (6 PCIe FPGA dev boards, only 2250 MH/s total) using my own software to get and send work to the pool (since my FPGA interfaces aren't supported by the popular mining apps).
If there's a plan to move to stratum only connections, I'll assume you'll give everybody a heads up before the old protocol is shutdown? That kind of news would get me off my butt and motivate me to actually revise my software to work with the new protocol

.
There are no plans to eliminate the non-stratum interface entirely. However, as more people move to Stratum, I may eventually change DNS entries and merge multiple pool servers together, eventually pointing all of the getwork connections to a single server. In this scenario, you would eventually lose the ability to run multiple BTC Guild servers as failovers, aside from one in the US and one in Germany.
Since I colocate my servers in Chicago and Dallas with multiple servers in each, this may never happen since it would not save me anything on operating costs, outside of possibly freeing up enough amps to fit another server in the rack without going over my limit.
