Installing pear packages via API

Dear Mapear-generaliling List Members! I have a question about pear: I use a lot of pear components in my web projects but can't be sure that others have this pear components installed (or even the pear base system like with php 4.3.x under windows). Is there any way to install all the needed pear without copying them to a seperate folder, but installing them when needed. So to come to the point: Is there a PEAR API available which enables php scripts to install needed pear packages (so the user doesnt need to use the cli)? and if not is it planned? what do you think about the idea?
