>- Some of the documents are things like detailed maps, drawings, aerial photography etc - highly graphical. Viewing these through an RDS connection is highly dependent on the uplink speed at the host, with complex graphics you have to be careful navigating through documents (use pageup/pagedown instead of scroll wheel etc) and you often see some raster-style screen redraws. By default RDS sessions are only 16-bit colour, so if you need to see documents in 24-bit or deeper you have to accept slower screen refreshes. If a user has to work extensively with a highly graphical document they can download it and view it locally. Still, RDS/RDP is highly refined and efficient. One installation has only a 5Mbit down/1Mbit up link at the host side but performance for almost all functions is nearly good enough to make you forget you're working remotely, and even viewing graphical documents is still quicker than having to download them.
And then there's the nag factor... every such document has to be preceded by a warning, of the "due to graphical nature of this document, parental discretion is advised." kind. (g,d&r)
