I am developing a tool that discovers network services enabled on host and writes short summary on them like this:

init,1
+-- login,1560 --
    +-- bash,1629
        +-- nc,12137 -lup 50505
{
    :net => [
        [0] "*:50505 IPv4 UDP "
    ],
    :fds => [
        [0] "/root (cwd)",
        [1] "/",
        [2] "/bin/nc.traditional",
        [3] "/xochikit/ld_poison.so (stat: No such file or directory)",
        [4] "/dev/tty2",
        [5] "*:50505"
    ]
}

It proved to be very nice formatted and useful for quick discovery thanks to colors provided by the awesome_print gem. However, its output is just a text. One issue is that if I want to share it, I lose colors. I'd also like to fold and unfold parts of objects, quickly jump to specific processes and what not? Adding comments, for example. Thus I want something web-based.

What is the best approach to implement features like these? I haven't worked with web interfaces before and I don't have much experience with Ruby.
