The 3.5 version of the IFolder Server has just been released as open source. Yah!
I’ve been wanted to running this for a while as it seems like a well tested system that works well with offline files and is cross-platform. There are even build instruction for Dapper, plus config details. Hopefully I’ll get a chance to test this some time in the next month or so.
Update: Notes on builder IFolder Server on X68_64. Unfortunately it looks a little tricky. Seems I’ll have to figure running a 32bit userland on a 64bit xen kernel. I think they might be some problems with 64bit modules and 32bit modutils, have to check in the mailing list. Also see this review with some good comments.
