I've done it many times and here was my experience:
1) The translation to DWF resulted in a huge image fidelity degradation. Most noticeably, none of the element layering works (so a sink with a white fill that masked the tile floor below no longer masks when saved as DWF)
2) Setting up the FTP accounts for each client requires a set of skills not common to many architects. It certainly took me a while. Be warned of cut rate Web-hosts with distant ESL tech support. I doubt that this system could be integrated into Google docs (I pay for Google premier services and I still don't think it can be done)
3) Client buy-in was tough. Getting them to try redlining, almost impossible. I have never tried to reimport redlines. However, some folks (trades people usually) liked it.
4) It is much slower than competing products I've seen from Autodesk.
The best part about this whole technology, untouched now by GS for years, is its integration with Publisher. I loved how you could press one button and have stuff sent to the printer and uploaded to FTP and made into PDFs, etc etc
