WPKG is a client-centred approach to software installation, so it does not support "pushing" software. However, you are free to issue Remote Procedure Calls to clients in order to trigger the start of the WPKG service or even directly the start of the WPKG command
===Software repackaging===
WPKG is about scripted, unattended installations. In our experience, repackaged software while running fine most of the time, might cause obscure problems in rare cases and leaves the admin standing without any reasonable support from the software companies creating the packages. [http://unattended.sourceforge.net/installers.php#repackaging This article at unattended.com] elaborates some in a bit more detail on this matter.
===Integrity or signature checking of installation packages===
This is a security feature and while surely a valuable gain, nobody has yet been found to implement it.
