Pando

A cool concept this "Pando". I haven't yet tried it out, but I often have to juggle attachement size. Of course, it works better on Windows with IE, but at least there is an OS X standalone. Not sure about linux.

Check it out at: http://www.pando.com/

The concept is simple.

1. Send an email to a friend, attach a large document with the Pando plugin.
2. Your friend gets the email, but with only a small attachment from Pando.
3. If your friends wants to, or has time to, he can open the small attachment and it will download the large, original attachment to his computer.

Nice idea. Keeps our inboxes clean from all the attachment clutter, and by passes all the attachment limits.
