[Blind-sysadmins] remote desktop solutions

Hello all: I would like to know what remote desktop solution do you use for helpdesk support? Do any of you use the remote assistance feature that comes with system center? I find system center clunky to use with a screen reader. In my experience, Window Eyes works the best with it so far. It looks like nvda remote is the most responsive right now. Is anyone using either nvda by itself or nvda remote in a corporate environment? I know there was a post on here about the nada remote relay server developed by techno-es.
