We use a fork of a pastebin software to make lenghty code and text pastes available to each other. We choose the original pastebin.com code base because of two things, it’s PHP and that it was fairly well structured to be hacked to be able to communicate with our rbot base irc bot.
Both the pastebin fork as well as the rbot plugin can be found at our mercurial repository.
Please note that the code bases uses different licenses, the pastebin is AGPL 3 and the rbot-plugin is MIT license.
