The best alternative to mIRC is X-chat- opensource:

Shareaza is free and very good, and you might also try an Mldonkey client, although their cores (especially the windows ones) definitely have some rough edges. But still the mldonkey core supports many protocols, and you can control it from ANYWHERE via a normal web browser.
