I've been looking for an initiative like this for so many years! Not even a month ago, I spent an afternoon looking all over the internet for somebody trying to build a native mail client for MacOs. Since DéjàVu from the lead dev of Sparrow, nobody it seems nobody has tried to do this. I haven't yet tested Mimestream but I already praise you for trying to do it! I will definitely give it a try and pay for it!
Me too! I used to order so much Ubuntu & Kubuntu Live CD's and handing them in my school. I was incredibly suprised that they managed to send huge boxes to me for free to Morocco and I was even more surprised that the unreliable post office of Morocco brought them to my house. They definitely came a long way, hopefully Canonical has been successful enough in the enterprise category that they manage to finance all of this till today.
