WiiConnect is a tool to connect Wii users to eachother, without the hassle of Nintendo’s “safe” crap. It will eventually be able to do many things (hopefully) listed below.

Features:

Homebrew Browser integration, or a homebrew downloader made by me if integration doesn’t work out
Chat (Hopefully many protocols eventually)
E-mail (POP3, IMAP, SMTP)
Public Profiles
News Reader (RSS feed reader, with a Wii News RSS feed)
Ability to poke other users on WiiConnect, no matter what feature they are using
And More!
