I was just browsing the ifolder web site and I stumbled on this link http://live.gnome.org/Banter/ Apparently novell is working on a new collaboration suite written in C#. I don't know if (or how many) ifolder devs were pulled for that project but it does mean less resources available for other C# projects at novell. I don't know why they continue on this path. Clearly C#/mono is not suitable for rapid development. They were supposed to release a stable 3.5 server over a year ago and they sill don't have one. They hinted at a stable 3.6 release for brainshare a couple of months ago and it's not even in beta. Nobody at the ifolder developers list will even attempt at hazarding a guess as to when 3.6 will be done. If you ask all you get is silence. You know it would not be too hard to slap together something like ifolders using subversion, you could even get locking for free. Only if I had more time....
