I didn't know there was a huge sms thread in here... I don't think it works in other country, we use our cellphones company API =)

If you read over this .. you'll see the extreme high interest. tho no one has ever really offered to fund any development ;-) there is quite some code work involved, some hours..

I know that there are Elgg sites that have used a squid cache for images. The primary constraint regarding the data directory is that all writes need to go to one location by default with Elgg. Think about it like database replication.

The only coding required for serving uploaded files/images on a subdomain is overriding the getURL() method of the file objects. You can do this with a simple plugin and have it return a url for the subdomain. Take a look at how the profile plugin overrides the URL for people's icons. Now, I haven't done this so it is all theoretical. There could be other issues that I'm missing. Let us know how this works out and if you have other questions.

I guess that I should be more specific, I am looking to do this work with tidypics, as I am using that plugin for the images on the site. I will have to look into how it manages it's files, as Profile icons and uploaded files can sit on the file server directly. I almost prefer it that way. 

Same applied for tidypics - you can override the getURL(). There may be a hard coded url or two in the rest of the code. I'm sure that will change in the next version of Tidypics.
