grandpa, we will consider adding a donation page if it becomes necessary. At the moment, we don't have any web traffic to speak of and we can get free hosting at sf.net and developer.berlios.de

More important than money will be help with creating the website and modifying the LimeWire MessageBundles for FrostWire (the FrostWire sources are currently located at http://developer.berlios.de/projects/limewire )

Sphinx, according to some of the folks at http://www.technutopia.com (the new BearShare forum) BearShare is still somewhat alive. They are still releasing new beta versions although the developers are currently not responsive.
