DHK I've just been using FileChute for several days. Previously I had used a web based service Yousendit.com, and then "graduated" to the file sharing of MobileMe. Filechute surpasses these because the file is in your control. At the yousendit site it was only around for a few days. At MobileMe it is given an arcane filename you have to send to recipients. Also, since it wasn't MY email that was sending the letter I was never quite sure whether the recipient got it. With filechute using my own email system I have more control over the message, as it remains in my sent folder.
That said the program is ridiculously simple to use. Drag a file to the "chute" on the app panel, and it asks whether you want to send the file straight, or zipped. I had already used the publishers zip program YemuZip to zip up files before I uploaded them to the web, so this just cuts out that step. I then get a web link from FileChute. I double click on the link, and I'm put into Mail, writing an email that already contains the link to the file.
There's even an iPhone app so you can see what's still on your Filechute folder.
Good product. Get it.
