<p><pre><code>    &gt; I want to have a server that checks
    &gt; every few seconds for a change in a
    &gt; file ...
</code></pre>
What file?  Be specific.  Facebook pages, Twitter pages, the all depend on who&#x27;s asking, and they literally change every time they&#x27;re polled.  So you would be pulling pages <i>all</i> the time, and most of those changes will be irrelevant, because yours friends won&#x27;t be looking at the time.<p><pre><code>    &gt; Now, I&#x27;d use a good hashing algorithm
    &gt; for my data.
</code></pre>
Why are you hashing anything?<p><pre><code>    &gt; I just don&#x27;t have the coding experience
    &gt; necessary. I would hire someone.
</code></pre>
You would need to explain very, very clearly what you want.  I know you think you&#x27;re doing so, but you&#x27;re not.<p><pre><code>    &gt; They would access the proxy, as I said.
    &gt; It would be through a browser that I
    &gt; either create, or just set the actual
    &gt; browser itself to the proxy. That&#x27;s
    &gt; hella easy.
</code></pre>
How do you know that?  You have no coding experience - how do you know it will be easy?<p><pre><code>    &gt; I could use my site&#x27;s SSL (expensive
    &gt; I know) to have a trusted website.
</code></pre>
It&#x27;s not the question of the connection being trusted, it&#x27;s other people trusting that the service you are providing won&#x27;t snoop on their data.  If I use your service, my data would be passed through your server.  Why should I trust you not to copy my data?<p>Why do you think existing video streams can be further compressed?  Why do you think images can be further compressed?  They form the bulk of existing data streams, so you would need a strategy to deal with them, otherwise you&#x27;re not gaining anything.<p>In short, and in summary, basically nothing that you are writing makes any sense at all.  Sorry if that sounds harsh.
