As long as you're using at least a 100Mb/s network (We use GbE), you should see a smooth experience. All works just as well as using a local machine, give or take some frames here and there. Just a forewarning, stay away from Google Chrome, and Chromium. They are awful to use with LTSP, you must deploy them as local apps as a fat-thin client solution, which isn't compatible with the Pi. The reasoning for this is that Chrome makes too many calls to the X server, and this causes horrible performance, you'll literally be watching chrome refresh, like loading an image over dialup.
