No wonder I was having a hard time to find it

Have you started a thread in the UPX forums that I can join?

I was reading the "our happy customers" forum and found that IM client Jabber uses UPX.

Do KIX developers read these forums, or is there a better way to contact them? I think it would be great if KIX had UPX compression from the source. Im able to test most things on my own but it would be reassuring if the entire community was there testing it with me along with the author.

We are involved in a number of projects - doubtlessly the most exciting being the NASA MER project, where we have designed and implemented the lossless on-board data compression module for the NASA Mars Exploration Rovers, better known under the names Spirit and Opportunity.
