[RC5] Amazon EC2 Configuration for GPU Instance

Indeed, I eventually got this working using the CUDA 3.1 client and is
currently ticking along quite nicely at 324MKeys/sec which is around 8200
units per day.
The spot price instancing by Amazon is very appealing for these GPU boxes -
the cost of running this one is $0.08 per hour.
It makes me wonder how massively this could be scaled up with enough funds.
I wonder if the internet would be interest in crowdfunding an initiative to
finish off an old cryptography project ;)
I notice the keyrate history graphs are still broken, and the mailing list
archive stops at August. Does anyone know if these are likely to be fixed?
