it is possible.
1. open a socket which call dropbox ip on port 80
2. send data via socket like this: (http Request Header)
GET /u/13000000/test.txt HTTP/1.1
Host: dl.dropboxusercontent.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: de-de,de;q=0.8,en-us;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate
Connection: keep-alive
If-None-Match: 43926n
Cache-Control: max-age=0
3. on socket are data, pick them
4. parse the http response
Here is a client ready but I have not tested it.
