I think this would be a great idea. I can think of a few features you could leave out for the lite version. You can of course take it or leave it.

Just hoping I am being the slightest bit helpful.

YummyFTP is by far my favorite FTP client and I am a recent Mac switcher. I searched and used all the different FTP Clients before I came to the decision to buy YummyFTP. It is by far the best client I have seen for both Mac and Windows. I think a lite version will really help those who are new to the Mac world and community. The lite version will definitely have an edge over the FTP client market right now. As awesome as CyberDuck is, it just can't take the abuse YummyFTP can.
