This would be awesome. [1]

Libcurl does support socks5, its fine. What i meant is: It is overhead
for me to write a socks5 proxy interface for the libssh2 thing so I can
use curl with it. It would be like:

curl -> curl socks support -> [socks proxy interface to be written but
considered overhead] -> libssh2

instead of [1]:

curl -> libssh2
