  1. More out of curiosity than of hope: has anybody any idea why SVs are almost unsupported on linux? By almost I mean that controls and indicators cannot be bound to shared variables, and that shared variables cannot be programmatically created and looked up. I know that SVs hosted on windows can be accessed in linux LV using datasocket nodes, but that is all it gets. And it has been said that datasocket is despicable. What are the missing pieces that make SV windows-only? I didn't find much in the canonical places, so I posted a dumb zero-kudos attracting idea.
  2. Hi, I'm wondering whether there is a way to monitor the SVE (or single processes/variables) on a per-client basis. The purpose of this would be network diagnostics or access control. I know the DSC module allows logging of data and events for shared variables, such as the very handy "value changed" event, but they contain no client-related information (to my knowledge), such as the client name or IP address. Are there any other shared variable events besides the value changed notification (e.g. "variable accessed"), which I have missed? Anyway, the SVE seems to be aware of clients, because it allows some access control through the DSC module (and with a bit of hacking even programmatically). You can define access control lists based on computer name or IP address, which is very buggy, but it works somewhat. Is it possible to somehow access this client information (number of clients, names/addresses and activities) from the SVE? I don't see any tools for that, but maybe there is an underlying API through DLL calls or whatever?
