Traffic Server has been out for a full week now. And it's been great, the interest is huge (almost overwhelming), and surprsingly, lots of people want to participate and contribute. So far, we've already achieved:

• 64-bit port on Linux!
• Port to Solaris (and OpenSolaris I believe)
• Port to Ubuntu (it required a lot of changes due to glibc changes)
• MacOSX port is partially done.

Not bad for week. If you are interested, check out our Wiki: http://cwiki.apache.org/confluence/display/TS/Traffic+Server.
