I have been working via VPN on weekends from home succesfully. It does take a while to STC, but opening your local and reloading all the links (dwgs and RS file) isn't too bad. Having a fast internet connection is a must. But it has worked fine. Have not had server issues. Network drives are mapped (for isntance Y is mapped to
\\servername\data\). I do have offline files and set the Y to be mapped every time (so my offline files appear on the Y drive as if I'm in the office). I don't have Revit offline files, don't even try it. The only issue I've been having is windows thinking I'm offline even while VPN is still running. Our IT said it might be due to packet loss (probably a cheap wireless router, or could be the DSL service). I just have to double click the icon on the tray and it does a synch and I'm back "online". Revit resumes as normal.
