emacs online

[Alex]

Dear emacs staff:

I was interested in making an online version of emacs for those without
linux or who just need to write a quick program online and save it on a
disk.  I was planning on programming this (using php) but needed help in
trying to decipher the *.el files which contain color coordination for
the emacs system.  Though I understand it won't contain ALL
possibilities of the emacs platform, my main goal is to create a free
online editor based on the already-designed and perfected emacs
platform.

Please tell me what you think and if there is any possible way you can
help me.  

Sincerely,

Alex S.
