+/******************************************************************************
+ * Notes about dojo.io design:
+ *
+ * The dojo.io.* package has the unenviable task of making a lot of different
+ * types of I/O feel natural, despite a universal lack of good (or even
+ * reasonable!) I/O capability in the host environment. So lets pin this down
+ * a little bit further.
+ *
+ * Rhino:
+ * perhaps the best situation anywhere. Access to Java classes allows you
+ * to do anything one might want in terms of I/O, both synchronously and
+ * async. Can open TCP sockets and perform low-latency client/server
+ * interactions. HTTP transport is available through Java HTTP client and
+ * server classes. Wish it were always this easy.
+ *
+ * xpcshell:
+ * XPCOM for I/O. A cluster-fuck to be sure.
+ *
+ * spidermonkey:
+ * S.O.L.
+ *
+ * Browsers:
+ * Browsers generally do not provide any useable filesystem access. We are
+ * therefore limited to HTTP for moving information to and from Dojo
+ * instances living in a browser.
+ *
+ * XMLHTTP:
+ * Sync or async, allows reading of arbitrary text files (including
+ * JS, which can then be eval()'d), writing requires server
+ * cooperation and is limited to HTTP mechanisms (POST and GET).
+ *
+ * <iframe> hacks:
+ * iframe document hacks allow browsers to communicate asynchronously
+ * with a server via HTTP POST and GET operations. With significant
+ * effort and server cooperation, low-latency data transit between
+ * client and server can be acheived via iframe mechanisms (repubsub).
+ *
+ * SVG:
+ * Adobe's SVG viewer implements helpful primitives for XML-based
+ * requests, but receipt of arbitrary text data seems unlikely w/o
+ * <![CDATA[]]> sections.
+ *
+ *
+ * A discussion between Dylan, Mark, Tom, and Alex helped to lay down a lot
+ * the IO API interface. A transcript of it can be found at:
+ * http://dojotoolkit.org/viewcvs/viewcvs.py/documents/irc/irc_io_api_log.txt?rev=307&view=auto
+ *
+ * Also referenced in the design of the API was the DOM 3 L&S spec:
+ * http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407/load-save.html
