PEAR_RemoteInstaller is a package that makes it possible to synchronize installations of PEAR between a local computer and a remote computer, even if there is no shell access on the remote computer. To do this, it uses PHP's ftp, ftps and ssh2.sftp streams to copy files installed locally to the remote system. This new version therefore requires PHP 5.1 or newer to take advantage of the power of ftp streams, and no longer depends on the Net_FTP PEAR package.
This version is essentially a bugfix release, as the initial versions did not in fact work with PEAR version 1.4.3 or newer (I no longer had a remote host that supports unencrypted ftp access with which to test it). Although it adds ftps and sftp support, it does not change anything about the implementation of the underlying code, or the commands. Future versions will be far more user-friendly and well-thought out.
That being said, it does work (finally), and can be used for those users who would like to take advantage of PEAR packages on a host that provides PHP and ftp or secure ftp, but does not provide shell access.
