Bespin is named after a fictional planet in Star Wars films and books. It first appeared in Star Wars Episode V: The Empire Strikes Back, and was the gaseous planet over which the floating Cloud City appeared.
I had a play with that phpanywhere, and i must say its superb.
I have used to to edit files on my servers, and even with a very good workflow. Its still in production, so there are some odd issues, one of them being mangling of some of my more wierd code (i write odd code anyhow).
It basically mimics the OSX application i love so much: Coda sans the online books, terminal, and the speed.
Speed is a real issue with phpanywhere, but to be honest, i'm not a savefreak. i am confident in large chinks of code i write, and i dont save very often for testing.
overall, when i'm caught out of the office, without my mac, and i need to edit some php somehwhere. its absolutely AMAZING.
I was actually thinking of you when i saw it Gabe ;) The only thing people were banging on about was security and it's like handing the keys over to someone else as it's a hosted solution. People are wanting it to be a downloadable script to up it on your own server.
