Official Motorola Library -- In TidBITS-322 we mentioned a PowerPC math library compiled from Motorola's PowerPC SDK. The library was later withdrawn due to licensing concerns and Motorola's intent to release their own version. Though it's a few weeks late, Motorola has indeed released LibMoto, which improves the performance of some floating point math functions on Power Macs. The shared library is available for free (a developers version is also available), although Motorola asks users to register online to download the library. If you don't do extensive number-crunching or graphics work on your Power Mac, you probably won't significant benefit from this library, but some users could see worthwhile performance improvements. I've seen unconfirmed reports of problems using LibMoto with the GeoPort Express Modem and some fax software (surprise!), so be sure to take normal precautions before installing this (or any) system software.

Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
