I am looking for a way to dynamically add content (specifically html tags) to a remote clients page(s) without actually having access to any of their files/server. I understand that it will require the client to install/place some sort of code/script on their side to allow me to do this. I am currently researching out SSI and it look like it may be a good candidate for the job. I am just wondering if this will work, or if anyone else has any ideas on how to efficiently accomplish this. I am a pretty good hacker/wanna be programmer and if I can just get an idea of what direction I need to head in I can usually figure it out. Thanks
