[Blind-sysadmins] Remote Desktop in the modern age

Hi, The recent discussions on here for remote desktop have lead me to ask this question. Are the remote desktop protocols used today giving enough in accessibility? I know we have RDP and Citrix capabilities, but to be honest I have seen very few Citrix implementations these days, and more and more is being done with custom web plugins, especially in the VDI space. What potential options do we have going forward, are the current access methods likely to become outdated and who was responsible/is now responsible for maintaining the access via the new protocols? Discuss. Andrew.
