Couple of Ideas

I have been musing over a couple of ideas for the past few weeks.

1) The first one had to do with alerts. Most of the WWW today is based on polling. I lookup a website and it tells me if it has something new for me. I wanted to create a website which would be an 'alerts network'. People can come and create alerts. Just like Google Alerts and probably weave networks of such alerts. Upon using Google alerts, I felt that alerts just throws too many things at you, whether or not you want. Thus we need something in between alerts and polling. A system which would capture your desired alerts and show just a summary of those to you upon your desire.

2) The second had to do with media micro-content. I usually work on three-four computers. Have my data all over the place. I was wondering if its possible to use this micro-content to provide a single interface to all my distributed data. For eg, I have some music on office PC, some music on my laptop, some on youtube, some on esnips.com and some on my mobile phone and the rest on an iPod. Suppose I create an XML based metadata which resides on a standard server. Essentially, it has to be accessible from any system. This XML would provide a virtual 'find-all-music-here" kind of interface. When I use some software to play a song, it would just look up where it is and play it.
