Well bizhat.com only allows up to 2 MB sizes and thats it, I don't know much about streaming but I know people use Winamp and win media player for this kind of stuff.
Just give info for them and such in your site and let them stream from your IP / PC and stuff.. Thats all I know about streaming.

If you need some file stroage space like 50 MB no size limit you can go to http://hosting.cfe-clan.com and check some stuff out.
