Hi Ramiro,
All things are _possible_ because fundamentally it's just data moving over a connection.
Of course some things might be more work than others. Email is easy because the work to implement POP3, SMTP and IMAP have been done. For other things the support for that protocol has not been done, so it''s more work to make it happen. but, as I say, it's all _possible_.
Personally I've not done any work in the field of streaming audio, so you'd need to investigate what protocols you want to use, and then implement them if you wanted to use them.
cheers
Bruce
