I can only speak for myself but if I had a project that was in maintenance mode and someone else wanted to re-implement it differently and take over maintenance I'd be thrilled. I gather PAR is still in active development so there's the issues of differing visions to complicate the issue. Anyhow, there is a very positive way to take this (whether that happens is different).

I just know I have very little "extra" time so I'm pleased as punch when other people sit down and do some work I'd otherwise do myself.
