Terrence Ryan has a proof of concept app (“CF AIR Compiler”:https://www.numtopia.com/terry/blog/archives/2007/11/cf_air_compiler.cfm) which takes CF sites and compiles them into AIR apps. His approach simply makes since and CF is probably the easiest language to accomplish this since CFHTTP and CFFILE are so freaking simple to use.
Although this is done with CF, for CF, and by CF (I only…with and by are the same thing but i had to complete the phrase; hehe) you could essentially point this to almost any site and pull the files (html content, js, and css) but it is cool to see this proof of concept in the wild.
