Auto-Dropboxify All Web-Downloaded Documents

I oftentimes download pdf presentations from the web, simply thus when I reopen them in my laptop later, I wonder if they got updated/changed inwards the meanwhile. It would be squeamish to accept a service where my local re-create also gets automatically updated/synced (a la dropbox) when the authoritative source re-create gets changed. (The deviation from the dropbox model is hither the source does non involve to cooperate yesteryear deploying a sync software, e.g. dropbox, or fifty-fifty hold upwardly aware that its document is beingness synced.)

So hither is my projection idea: auto-sync all web/url downloaded documents, so the downloaded local re-create of a file is kept up-to-date alongside the authoritative copy on the web. I recollect many people volition reveal this useful. Some other examples of documents downloaded from the spider web in addition to would create goodness from auto-updating include: metropolis documents (e.g., street-parking rules, garbage collection rules, etc.), number calendars, taxation documents, CVs. (Do you lot accept any other examples?)

This shouldn't hold upwardly also difficult to build. A completely client-side solution is possible. A client-side software that keeps rails of web-downloaded documents, and periodically checks alongside http to notice whether whatever of these documents got changed would create it. If a alter is detected, the software should download a copy, in addition to should prompt the user when she opens the local document side yesteryear side about whether the updated or the former re-create to hold upwardly used.

Of cast a cloud-hosted push-based synchronization solution would hold upwardly more scalable in addition to efficient. This would hold upwardly also to a greater extent than gentle for the master content provider equally instead of thousands of client-side software periodically checking for updates, alone the cloud-hosted synchronization service volition depository fiscal establishment tally for the update to the document. Upon detecting an update the cloud service volition force the updated document to all clients that posses this document. I am certain at that topographic point are a lot of details to run out to brand this service efficient. And at that topographic point may fifty-fifty be a agency to monetize this service eventually, who knows? This cloud hosted synchronization service sentiment may hold upwardly seen equally extending the CDNs to accomplish out and embrace the pc/laptops equally the terminal hop for content-replication.

A farther generalization of this "auto-sync documents downloaded from the web" sentiment is to allow whatever host to modify/update the document in addition to yet even thus maintain the other copies inwards sync/up-to-date. This thus turns into an application-level virtual-filesystem that is web-scale. And implementing that would hold upwardly to a greater extent than tricky.
