Developers must collect device information (the "UDID", aka their unique device identifiers), register that device at the iPhone developer portal, create an special provisioning certificate, add a special entitlement, and build an ad-hoc only version of their software to distribute along with that certificate.
If all that seems like a hassle, well, yes it is. It is, however, the proper, authorized, and recommended way to distribute pre-release software, whether for testing or reviews. But there is another way.
If you know for sure that your target audience is another developer, the process becomes way easier. You can simply compile a normal development build of your application and send a copy of that build to another developer.
That's because each registered developer has the ability to sign applications. Although the app was built to work with just the in-house devices you've registered for development, another developer can re-sign that application using the simple command-line script shown here.
codesign -f -s "iPhone Developer" $1.app
This script uses Xcode's codesign utility to sign the already compiled version of the application. Once applied, you can then install the application through Xcode.
So is this a general distribution solution? No. And thank heavens for that; free trading of app binaries would rapidly lead to piracy. This approach allows developer-to-developer testing and collaboration only. The development signing is limited to the units you have personally registered.
If you want to try this out, follow the link at the start of this post. It leads to a testing folder I keep around and occasionally stock with software that I need tested. It also includes a copy of the script, which you must make executable (chmod 755 signit).
