Just FYI and in case, I use a great little cli tool called pngnq to compress pngs. Works great, very significant compression ratios. It's in the debian/ubuntu repos (sudo apt-get install pngnq).
Here's the homepage: http://pngnq.sourceforge.net/
Interesting tool! However, if anyone is going to use this on screenshots or whatever, please keep in mind that this tool is lossy (that is, it reduces the number of colors used and therefore you generally lose some information). From what I see on the site it gives pretty nice results, but for screenshots that show off Inkscape (and/or artwork generated by Inkscape) it might not be appropriate.
No way I would use it if it was going to be lossy (at least I don't use settings that would cause any visual difference). And yes... I have compared side by side and there is no difference.
