I have owned Rumpus since late 2007, but started using it in 2008. Rumpus is one of those things that you may have around your home or office and never fully grasp the full value until the light bulb goes off. Well, in the case of Rumpus, once you start using it, the light bulb will continually go off. The use cases for this application are only limited by your creativity and imagination.
If you are a business of any size, the price is truly “a drop in the bucket”. The developer is simply outstanding, and the product is pure gold. It is so solid, that I never hesitate to install a beta.
If you are a small business or consumer and are paying for MobileMe, Dropbox, or any other on-line file syncing/storage solution, Rumpus deserves your consideration. Yeah, I seen some posts where users whine about the cost. I paid for it, and continue to pay for every paid upgrade because it is absolutely worth it! Of the over 150 paid applications on my HD, Rumpus is at the top of the list to keep current.
The only thing that I can say would be a slight barrier for the average user, would be that some technical knowledge and a little patience is required in order to set it up. The reason for this is not that the product is overly complicated (it isn’t), but rather that some knowledge of server provisioning is needed in order to get it working. For example, if you do not have a static IP address, and some understanding of DNS settings, you should allow for a bit of time to get things working. Other than that, it is easy to administer once you have it up and running. If you are unfamiliar with basic networking and are afraid to learn, then you should consider hiring someone who can set it up for you.
The most amazing thing about Rumpus is the developer - 7X24 around-the-clock support!
