Web Browser Access

[Bluebie, Jenna]

I'm thinking about web browser access, for instance, links that make  
things happen in shoes apps. I'm wondering if it's reliably possible  
to make ajax requests to localhost:someport in webapps hosted on  
internet domains? That would make for a pretty nifty way of sending  
shoes apps data, and even possibly returning data back at the end,  
essentially turning Shoes in to a simple web server with camping-like  
functionality.

It occurs to me though that this is all stuff which could be  
implemented in pure ruby, as it is in camping itself! Maybe this could  
be a fun little gem to build for desktop apps that communicate with  
web pages. We could even marshall the data in to json and make it  
somewhat JSON-RPC 1.1 compliant, be kinda nifty! :)

I can imagine a LAN based IM app that would send messages by making  
http requests to the other user's shoes instance that call a method  
which adds a message to a stack. Fun fun.
