Oh, before I begin: SIP 0.4.1 has been out for a while. Basically a bugfix release compared to 0.4.0. About project activity: Well, I'm at the end of my PhD, and have code to release for http://vxl.sf.net soon. I'll keep the effort to support SIP for Linux from our source package. I'll try to get a job that helps boost SIP to the next level. No guarantees, but it's in my mind! Happy end of year!
