Kato.im is a great new team chat platform. Here are two scripts which you can use to mirror communications between one room in Campfire and one room in Kato to ease the process of switching to Kato.
I wrote these in a hurry, so please the use of both Groovy and Node.js. Contributions and upgrades are 100% welcome!
#####campfire_kato.groovy usage screen campfire_kato.groovy
Note: I tested this with Groovy 2.1.6
#####kato_campfire.js usage npm install nan npm install request npm install util npm install /path/to/ws screen node kato_campfire.js
Note: This requires my patched version of the ws websockets library. Hopefully my pull request will be accepted into mainline soon and this will just work out of the box.
