 ## Is it possible to use them as a mounted drive with FUSE?
 
-Well, actually they can be used in such manor. Because they are similar to 
-[AWS S3](https://aws.amazon.com/s3/) many tools are available and you can find 
-many articles and [Stackoverflow items](https://stackoverflow.com/search?q=s3+fuse).

 ## Observations and conslusion
 
-Using Spaces in this way makes it easier to access and manage files. But 
-besides that you would need to write additional code to make this one play 
-nice with you applications.
-
-Nevertheless, this was extremely simple to setup and use and this is just 
-another excellent product in DigitalOcean product line. I found this exercise 
-very valuable and am thinking about implementing some sort of mechanism for 
-SQLite, so data can be stored on Spaces and accessed by many VM's. For a 
-project where data doesn't need to be accessible in real-time and can have 
-couple of minutes old data this would be very interesting. If any of you find 
-this proposal interesting please write in a comment box below or shoot me an 
-email and I will keep you posted.
