 iScheme is built on top of an R5RS [[http://soft.vub.ac.be/soft/skem|Scheme]] implementation that is developed at our lab. It supports Scheme and Objective-C interaction, thus enabling access to iPhone APIs (e.g., GPS, SMS, phone) from Scheme while bringing Scheme's well-known benefits (higher-order functions, structural macros, automatic garbage collection, etc.) to the iPhone development. iScheme provides a distribution layer that employs an event-driven style for peer-to-peer service discovery, asynchronous remote messaging, and timeout-based failure handling.  iScheme is built on top of an R5RS [[http://soft.vub.ac.be/soft/skem|Scheme]] implementation that is developed at our lab.

 The ''remote-send!'' function takes as argument a remote reference, a function name, and optional variable number of arguments. In this example, the ''submit-news'' function iterates over a list containing news articles to be published, and invokes the ''receive-article'' function on the ''publish-ref'' reference corresponding to the newly discovered news publisher.  The ''remote-send!'' function takes as argument a remote reference, a function name, and optional variable number of arguments.

 The ''remote-send'' function works similar to the ''remote-send!'' function but it returns a //future// instead. The ''when-resolved'' function registers an event-handler which is executed when the future is resolved. The ''remote-send'' function works similar to the ''remote-send!'' function but it returns a //future// instead.

 ===== What about Apple's License Issues? ===== ===== What about Apple's License Issues? =====
-iPhone apps developed in iScheme do not require any modifications to the iPhone OS, therefore, they can be deployed to the iPhone like any other third party apps. So far we have used Apple's iPhone Development Certificate to deploy applications to real devices. Even more good news is that, as of June 7th, 2010 the Apple iPhone Developer Program License Agreement stipulates that applications may embed interpreters, which means that iPhone applications developed in iScheme can be submitted to the App Store.  +
