Great tips on cloud sharing. I find dropbox isn't as nifty as a newer service called 4Sync (which stems from the worlds largest online storage site 4shared). 4Sync gives me 15gb of free storage just for registering and is extremely easy to use, I highly recommend it over the other alternatives you have listed above.
Thank you very much for this article!
I loved using imesh, but today M$ decided to end it >.<
Since SkyDrive offers the largest free solution, you technique makes it all possible.
I hate, but really hate, the cloud storage system that makes you copy all your folders to the "cloud" folder. Its annoying!
With your lovely shell extension its all possible again!
