Anyone already have a Satellite API script to download packages?

I figured I'd post to ask before anyone goes off to reinvent the wheel here.

Does anyone already have a script in use that uses the Satellite API (namely packages.search and getPackage) to pull down rpms matching an expression?

I have a user agitating for the ability to pull some 3rd party (Puppet) rpms from the satellite en-mass so that he can dump to ISO for offline hosts.

Thanks!
