[and it will save OpenCL kernels from rewriting for NV ]

Yes, though when it comes to that you may need to be backporting some of my experimental code, so don't get too complacent there :P

LoL ;D

What ( if anything ) do i need to add or modify in my config.xml file to get
2 instances running on my GTX460 ? Taking into account that the other card
is a GTS250

you won't have to modify your app_info.xml at all, there's now a 32 and 64 bit installer in the Beta area that should do the job for you ;) Big thanks to Jason, for that one! Although you should make sure that either you run your cahce down completely, or ensure that your plan_class and version_num match the following before you run the installer:
608 and cuda
609 and cuda23
610 and cuda_fermi
As me and SciManSteve found out, having the incorrect pairing of plan_class and version_num will trash your entire cache of tasks.
Or if your feeling really brave there is another way to make sure that you have the correct pairing, but its quite risky and could end up trashing your cache anyway
Think your struggle to get 2 wu's running running on the 250, never had one myself, but it wasn't worth it on my old 260, and unfortunately, there's no known way at the moment that I'm aware of to run 2 wu's on 1 card and only 1 wu on another

Doesn't work.
See http://setiathome.berkeley.edu/forum_thread.php?id=61184&nowrap=true#1027766
[EDIT] AFAIK there is only minimal performance gain running two or more tasks on a 460.

Saw that thread, but haven't been over there since, did the GPU_RAM suggestion by Joe not work?
Edit, just read the thread, shame, I was thinking about plugging my 260 back in
