well im talking about an app that the general user can have running on their machines, almost all the time. To have an complete webserver with script addons running is just too bulky.
This would also mean that Gwebcachings are ensured for all future.

This app would not, i think have an entire HTTP server implemented, i think again, runned in a somewhat crippled fashion, just to hold down the resources it uses. Very much smaller then the Limewire app itself.

Also this app should take into the account that most peoples Ip adresses are changed more often. Me for an example i have ADSL 512 k connection and my Ip have changed without pre-notice shall we say every 6 months or so. Im always connected 24-7.
