I got an email from Windows Live today detailing some free online services for members.  The one that caught my attention is 
SkyDrive, a 25-GB online storage space which includes a public folder.  I had to do nothing at all to access it other than agree to the terms of service.  (I actually read that for once.  It's obvious, harmless stuff.)  This may be a good way to give each other stuff.  I think we all have Live in one way or another, we've "friend"-ed each other, and we know who we are in real life more or less.
I still don't know how to point you to my public area, where I uploaded innocuous files of several types to see if anything would stop any of them.  I imagine some of you also received the same email.  So yeah, whatever.  Just throwing it out there.
. . .
Edit 2:  I think 
this will work.
Yes it does.  So no need for Live or anything else to link this stuff if it's in the public folder.  Cool.
Edit 3:
Direct link to an image . . . also works.
Direct link to MP3 . . . also works.
Hell, this beats my nerfed Roadrunner webspace by a mile.
