Sure there are tons of modules but where's the fun in that?
Seriously, I don't think there are modules for CuteMX or iMesh. Those protocols are completely undocumented ... I reverse engineered part of them (enough to search and download).

The MP3::Napster is more like a client (just like the PSX client, for Scour eXchange)

And as always, I like my code better ... because it is ;-)

Have fun,
