Thanks for the reply. However, it's not the sharing, but the *searching* that concerns me. You can share any kind of file you want. But when searching for "audio" files, ogg results are not returned. If you search for "Any Type", oggs are, of course included. Its certainly understandable that the Limewire developers started with the most popular format, encumbered by patents as it may be. However, support for a truly open format (ogg) seems like a next logical step.
