Hi Dow,
the version currently in CVS isn't usable for production runs due to a
couple missing features (most notably, 1-4 exclusion). A fully working
implementation is scheduled for namd 2.7beta2; while I don't have an
exact release date, I've been informed that there will be heart attacks
if that hasn't been released within 3 months, so that should give a good
rough estimate.

A problem exists with scheduling processes reliably on gpus but is possibly being addressed by the Phoenix application development framework. So, I think from reading these papers that it is just a matter of time before NAMD/CUDA becomes available as "stable". It is not clear how long that will take and if NAMD 2.7 would be released with a CUDA enabled "stable" set of features.
